Running Seatable 5.2.7

All of my n8n integrations started failing today and not only on my seatable but also on clients seatable installations (self hosted) as well.
I can see this in the logs

and this is the view on n8n side.

This is a bit of a problem as I have no idea where to start looking into the issue. It’s strange that all of it started today on all seatable installs at once.

It turned out, that the nginx location block for the /api-gateway was missing.
Why the system stopped working night, is not clear as nobody touched the system.

yes, a typical “RTFM”
It’s mentioned in the 5.0 update: Extra Upgrade Notices - SeaTable Admin Manual
looks like I did do it on one upgrade but forgot it on the rest.

I just also noticed the newsletter that came a few days ago mentioning the deprecation of the old API in 5.3: Switching to the SeaTable API gateway: What changes with version 5.3
I still didn’t think to much of it as I usually do read the upgrade instructions.
my bad.
