Hi there,

I hava a problem with adding a remote to my projects.  
in particular with the login

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/a/c/ac4e3a138ab0bd40110b93905a74aa274c2904d7.png)

I did create a new key, added it to GitHub,.. and so on.  
is there a way to debug, why it is not logging me in?=

greetings form stuttgart

Have you checked the node-red log output and the browser's javascript console for any related error messages?

i do run it in Docker 🙂 does this make a difference?

The image I am using is custom Build:

docker pull echteler/nodered\_balluff\_ui:latest

Login Balluff  
Pw: Balluff1

It is some sort of play arround image for exhibitions and demos

hi there,  
did dig in it a bit more:

git log shows:

```auto

```

manually Creating an ssh key, adding it to ssh and so on (as written in the GitHub manual) works fine.  
also git clone with the newly added key from command line works.

any clues?

```auto

These are hard problems to debug. Given the complicated way we interact with the git command-line, we do occasionally discover ways it can fail unexpectedly that don't fit with any of the existing ways we handle.

When you get the error in your browser log, can you share a screen shot of it?

> Failed to load resource: the server responded with a status of 400 (Bad Request)

I would expect the log message to contain a bit more detail than just that - maybe it needs expanding out?

If not, switch to the Network tab in the browser console and find the same failing request - see if there's any more detail in the response of the request.

I cleared the network tab, then entered my PW for the ssh key...

this is the output of the network tab:

</div>

one more thing I tried:  
from command line `git push -u origin master` did not work (auth problem) until I manually added the ssh key that I created in node-red to the ssh client...

```auto
eval "$(ssh-agent -s)"
    > Agent pid 59566

ssh-add .sshkeys/Balluff_testNR (keyname)

```

after adding the key manually git push -u origin master succeeded.

This was I was hoping to find. `Host key verification failed` is a known error we don't handle very well.

I assume you've been running all of the git commands within your Docker container? Do you recall ever seeing a message about accepting the Host key?

You could try adding the github rsa key to your local known\_hosts file. I think the following would do it:

```auto
ssh-keyscan -t rsa github.com >> /etc/ssh/ssh_known_hosts

```

I tried adding:

```auto
RUN mkdir /root/.ssh && chmod 0700 /root/.ssh && \
    ssh-keyscan -t rsa bitbucket.org >> /root/.ssh/known_hosts && \
    ssh-keyscan -t rsa github.com >> /root/.ssh/known_hosts

```

to the Dockerfile, but with no success. still an error.

still the same:

```auto

    "code": "git_auth_failed",
    "message": "ssh: Could not resolve hostname github.com:echtelerp: Name does not resolve\r\nfatal: Could not read from remote repository.\n\nPlease make sure you have the correct access rights\nand the repository exists.\n"

assuming all of the above, I would guess, that my in node red generated key has not been added to the ssh client? could that be possible?

Just as a note, I have the exact same issue with the official Node Red container on a raspberry pi.

steps to reproduce:  
on a clean raspberry pi:

1. docker pull nodered/node-red
2. docker run -it -p 1880:1880 --name mynodered nodered/node-red
3. docker exec -it mynodered /bin/bash
4. nano /data/settings.js  
4a) change the projects enabled to true  
4b) exit nano and save changes (ctrl+x -\> y)  
4c) type exit to leave the container
5. docker restart mynodered
6. open browser and go to node red,
7. create new project:  
7a) Enter GitHub username and email  
7b) project name and description  
7c) flow file  
7d) passphraze
8. generate new ssh key
9. copy ssh key to GitHub
10. add remote in projects settings
11. do first commit and got to the arrow tap to select remote
12. after the loading bars run through, the passphrase for the ssh key pops up.  
enter key, nothing happens and this error comes up in the network section of red tools.

```auto
{
    "code": "git_auth_failed",
    "message": "ssh_askpass: exec(/usr/src/node-red/node_modules/@node-red/runtime/lib/storage/localfilesystem/projects/git/node-red-ask-pass.sh): Exec format error\r\nHost key verification failed.\r\nfatal: Could not read from remote repository.\n\nPlease make sure you have the correct access rights\nand the repository exists.\n"
}

```

System Node Red is running on: new clean Raspberry pi.  
client: MacBook Pro, 2019, safari 13.0.5.

hope this helps also 🙂

Except that isn't the same. That is failing to look up the hostname - not the host key verification error you had previously.

Curious the hostname it says it can't find is `github.com:echtelerp` - why is it including "echtelerp" in the hostname suddenly....?

probably because I added your suggestion to the Dockerfile:  
its an additional RUN to use the ssh-keyscan.  
after adding that to the Dockerfiles the error code changed.

my post should have been still an error. I changed it 2 lines above, 🙂

I just had done it over again:  
after clearing the container, and redoing the above procedure I get:

```auto
{
    "code": "git_auth_failed",
    "message": "ssh_askpass: exec(/usr/src/node-red/node_modules/@node-red/runtime/lib/storage/localfilesystem/projects/git/node-red-ask-pass.sh): Exec format error\r\nHost key verification failed.\r\nfatal: Could not read from remote repository.\n\nPlease make sure you have the correct access rights\nand the repository exists.\n"
}

```

The hostname thing came probably by my playing around with the git settings inside the container.  
so maybe it was by accident.

Ok, so I think I'm going to have to try to reproduce this following the steps you've provided. Not sure when exactly I'll be able to do that - possibly tomorrow.

Any help I can provide I will 🙂  
Due to corona I'll be I home office for a while, so I have all my toys around me.  
should I make you a screencast tomorrow?

I can recreate the issue using own docker image and the steps you describe. Thanks for providing those.

If I run:

```auto
ssh-keyscan -t rsa github.com >> /usr/src/node-red/.ssh/known_hosts

```

it will add the appropriate key to the right known\_hosts file and it starts to work.

I did get the 'Could not resolve hostname' error once, but I wonder if that was some local dns caching because I can't reproduce it.

ssh-keyscan -t rsa [github.com](http://github.com) \>\> /usr/src/node-red/.ssh/known\_hosts

We can also create route folder by name known\_hosts in docker and then run command on docker

ssh-keyscan -t rsa [github.com](http://github.com) \>\> /usr/src/node-red/.ssh/known\_hosts

Which will solve our docker image error.

I have a similar problem trying to connect to a git repo on an azure devops site, using **https**.

when pushing the manage remote branch button, I get the authentication windows pop-up.  
on entering the username and password nothing happens after confirmation. I get the same authentication window again.  
no info in the node-red log console.  
in the chrome devtools logconsole I get the following error message:

`GET http://localhost:1880/projects/TEXbox_EventService/branches/remote?{} 400 (Bad Request)`

running the same get directly in the chrome browser I get some extra info:

```auto
{
* code: "git_auth_failed",
* message: "error: cannot spawn C:\Users\psmt\AppData\Roaming\npm\node_modules\node-red\node_modules\@node-red\runtime\lib\storage\localfilesystem\projects\git\node-red-ask-pass.sh: Exec format error bash: /dev/tty: No such device or address error: failed to execute prompt script (exit code 1) fatal: could not read Username for 'https://xxxxxxxx.visualstudio.com': No such file or directory "
}

```

running on windows 10,  
node-red v1.0.6  
git version 2.14.2.windows.3

from a git bash in the project folder I can push to the remote.

Any suggestions? Am I doing something wrong?
