As of 1 day ago suddenly can't see installed custom nodes, can't download/update any custom nodes

Suddenly I noticed today that I can't check custom nodes installed nor can I see any custom nodes at all, nothing works.
The stranger thing is I have not updated my comfyui installation at all, i've not installed any new custom node packages etc. the entire portable folder on my PC has not been modified (to my knowledge) in a while.

Did something change in the server side of things and the .json files being fetched now no longer works with somewhat older Comfyui manager versions?
(I am on the manager version that's from a few months ago)
Could somebody confirm if this is the case?

Here is the terminal log:
