Dear all, I have a strange behavior of Influxdb2, every time I open the webpage to Node-RED the Influxdb2 node shows up with red error sign. But if I only refresh the settings, then it goes away. If I refresh the webpage it comes back, and so on...
I'm running Node-RED as a container under Docker, as well as Influxdb2.
Thank you in advance for your answers.

Can you show us the node red startup log please? That is the one that starts with the Welcome to Node Red message. That may tell us something useful.
of course

I suggest upgrading to the latest version of node-red (3.1.3). It may not make a difference, but is certainly worth doing. Are you using the latest version of the influxdb node?
What does the influx node config look like?
Do the influx nodes function correctly?
Node-RED and Influx upgraded to newest.

same behavior
The influx nodes are receiving data and I see the data in influx, that's no Problem.
No it isn't.

Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

But in Portainer still says it is the older one
What does it say at the bottom of the dropdown menu in the node-red editor? That will tell you what you are actually using.
You mean this?
Then 3.13
Yes, so you are running 3.1.3, whatever portainer says.
What version of node-red-contrib-influxdb are you using? You can see that in Manage Palette.
0.6.1 is the latest, so it isn't that.
If you open the Developer Tools console in the browser and refresh the page do you see any errors there?
Are you able to try a different browser?
Console is where any errors would surface
That looks ok. Select the failing node and Export it and paste it here. Then we can import and see if we can replicate it.

Your influxdb server node is missing a hidden field database. Did you create that dbconfig in an earlier version and upgrade it, or something like that?
If, in an influxdb Out node, you click the server field and select Add New and then create a new one with the same settings then it should fix the problem. Then change all the other influx nodes to use the new one. Finally you can delete the unused one in Configuration Nodes in the node red dropdown menu.
