I'm having a problem managing the certificate with the fortigate firewall. the new firmware version 7.0 has the ability to manage, create and renew certificates in ACME mode, only I always get an error:
Error (The key authorization file from the server did not match this challenge "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" != "xxxxxxxxxxxxxxxxxxxxxxxxxxx on Fri Oct 1 16:11:20 2021 (UTC)
does anyone have the opportunity to explain to me how to proceed?
Yeah, I deleted it because I think what you're dealing with (trying to get a certificate on Fortigate) was actually different than the thread that I'd linked to (which was issues with Fortigate firewall SSL interception not liking sites that chained to the expired root). So I don't think my message was actually useful or correct, so I deleted it.
I'm not familiar with Fortigate myself, I was just trying to point related things together.
in the fortigate guide it would be enough to enter 3 parameters and the wan port where to accept the ACME renewal, but I can't understand what letsencrypt expects, if you need to create a txt file, modify the dns or other.
