Error 502

I was working with Content Templater and saved a change when the 502 error popped up.
Now this extension is no longer able to load.
I don't see any other problems with other extensions.

All updated to latest versions.

The Website is:
sommaruga.eu

I enabled:
- System / Debug System = Yes
- Server / Error Reporting = Maximum
- Loggin / Log Almost Everything = Yes

I then called Content Templater again to throw the error again, but in /administrator/logs I don't see anything related to this problem.

Here the data.

I don't use FTP, but SSH. I have to create the user.
But can you see what's the matter in the meantime?

I entered new info.

There shouldn't be IP blocking; there is not even a Geo block or even an access limitation.
I'll check better, meanwhile give me your IP.

I don't know what to say.
Now I'm asking others to do some tests, but the site is active because we connect from PCs and smartphones.

Meanwhile the technician who checked found nothing wrong.
Perhaps there is a problem for those residing outside the EU because they do not see the GDPR request for cookie approval and cannot connect without it. That's something I need to check.
If you give me your IP and your Country, I will try to do some further verification.

I saw that now everything is working extension.
So I should get a future update, right?

May I know what was the problem?

Thank you very much for your help and your patience.

If you're in the EU, it's strange that it's the GDPR. I will investigate.
Thanks again.
