Last night my ISP performed some kind of maintenance that gave me a new static IP address, and since then all of the Docker containers on my server are now showing "not available" at the "version" row. It looks like this:

 

I have already rebooted the server a couple times and also changed the DNS configs from my router's IP address to 1.0.0.2 and 1.1.1.2 because i read a thread on this forum that this solved the same issue for someone, but unfortunately for me that did not solve it.

 

Because i was doubting wether my server had proper internet access i did a 'wget google.com' command in the console and that does work fine:

I have attached diagnostics. Thank you very much in advance.

Oh, this suddenly over-night solved itself. Containers are showing "up-to-date" and "Apply update" again.
