Error 520 problems - no solution since months

Hello,

I posted our error here:

But I got no solution so far. The 520 error appears every day again (when I am saving something in our WordPress backend.

This page I got problems with: https://www.unaufschiebbar.de/

Here you find a screenshot of an actual error message (12/10/2021 15:02:52):

What can I do?

Best regards,

Christian

I am still baffled by you saying your server address does not end in 73.

Hi, I am deeply sorry. I don’t know what this means and above all what I can do if this fix the problem.

Could you please advise me?

I have now put the security option from here:


to here:

But after that, I get “Error 526 Ray ID: 69decb75caa45b4a • 2021-10-14 06:36:41 UTC
Invalid SSL certificate”

Would it be working if I am ordering the “advanced certifiacte mnager” for 10 $ pe rmonth? Or what should I do to prevent the security issue?

That’s precisely because you have an invalid certificate on your server. You need to fix this and configure a valid one.

Why you should choose Full Strict, and only Full Strict has all on that.
