Usually don't get verification code to log into website

I'm on a PS5 account, and therefore need to log onto the site via the Playstation Network to be able to post in the forum or use the trade search. However, it's often a huge hassle to actually log on. Why? Because it takes many attempts to get the verification code on SMS on the phone. Maybe this is more of a Sony issue than a GGG one, I don't know, but it's very frustrating.

All I get is a not-very-helpful error code about "Can't connect to the server" and a long string of characters.

If the site kept me logged in, it wouldn't be such a big issue, but I need to log on via PSN each time. And I've seen many others with apparently the same issue.
