Getting help
Until a few days ago I was having all the success in the world with my NextCloud on my Docker inside TrueNAS Scale.
Today I went to update, it’s been giving me this error constantly since I did this update today.
I made a few searches and I didn’t find any specific resources to solve my main issue, so this is tho help me and help others who faced the same issue like me.
The geral and main resources that I find its something like this one:

Not sure but maybe something with wrong internal rewrites Like this one:
