I ran Node-RED on a Pi, it ran fine until last night. After a deploy I lost the connection to Node-RED. And it can not be called up until now. I can start node-RED but I can not reach it via the browser anymore!  
What can I do??

you have a warning

Projects disabled: editorTheme.projects.enabled = false

Maybe it's this

But I don´t know, whats the warning means

I think this is not the reason because if I change the editorTheme setting in the settings.js file the warning change to:  
No active project: using default flows file.

but there is still anoher warining, but no comment with indicates.

it appears only: the date - [warn]

Projects disabled =false is fine.  
You can read up about the projects feature in the blog (see top of screen)

Step 1 the basics : the ip address that Node-RED is now running on is printed in your screenshot.  
Have you double checked that’s the up address you are trying to access?

After that what had you done before your last deploy?  
Was it installing an extra node? Upgrading a node? Using a new node?

If not you have two nodes with errors ui\_bild and  
securedhttp . I’d start by uninstalling them and seeing if the problem goes away.

I have triple checked the ip address,

the two errors have been there for a long time.

I recently added something to the topbar, and after a deploy, the connection was weng and I have not been able to grab it since.

I have no new nodes or similar installed or updated

What did you add to the top bar?

Try starting with a new flows file. Move your current flows file to a different name and then restart node-red

in the settings.js file under flowFile I write a file name and copy into this file my flow and save it under ~ / .node-red?

Well the good news is that its not something in your flow so you can move it back.  
and Node-red is running you just can't access it.

This means it has to be something in your install.

Have you installed any "dashboards" recently - any other nodes that say they have dashboard functionality. If so I would start by removing them ( and removing the two that Node-RED is complaining about as well)

No the only dashboard i have installed is the node-red-dashboard.

after I removed the two they are still in there!

Those are just warnings (about the nodes you removed). They should not appear again.  
By the way it is better, if possible, to copy/paste here rather than insert images. You can copy/paste from the terminal using Ctrl-Shift-C. When pasting logs use the same technique for making sure they show ok as is used for code/flows.

That warn is about the following credentials message.  
I see you have an error there still

Do you know what that is about? If not then you can search for the node id (86a81de6.9ee2d) using the Search feature under the hamburger menu to find that node to see what is wrong.

what is the hamburger menu?

this would have to be because i used the node-red-contrib-user node. Actually, I also uninstalled this

Do you mean you get this message after uninstalling? In which case there is likely an unused config node left. When you click Deploy you should see a message saying Unused Config Nodes. Click that and it will take you to it so you can delete it. Alternatively you can get to the config nodes from the hamburger menu and will see unused ones. To delete it open it and click Delete
