They come from an unique access via the following command :
cat ../nextcloud-data/nextcloud.log | grep "ZqzuTYMzM00Kfs2X8h25igAAAAg"

The error is coming from the optional app user_saml.

When did the problem start?

Is this a new installation or did this work previously?

It started 4 hours ago and it was working perfectly for about 2/3 months.
After disabling user_saml it worked perfectly again

I should have investigate it a little more.
It look like the app user_saml was the issue, i disabled it through occ and i can now use the application like before.
