For a while I’d get locked out on USA Sundays without fail from home address ( overseas user ) . It would take 12 hrs to three days before the “connection refused” would clear. Suspect possibly load related and credential check timing out. Got hit by cloud flare blacklist also which I find amusing , looks like it can be overly sensitive if it’s not tuned.
But there is also a couple of ip address reputation tracing services that frankly should get off the internet which feed some of the protection providers which could be contributing to cloudflares blocking of legit users.
Eg , try this site and put your ip into the end of the url

Looks like everyone in my suburb has a score of 58 out of 100 including my own ip ( that’s not my ip btw ) . These company’s are giving low scores to entire ISP address ranges and then on selling services to major cyber protection suppliers.
Meanwhile looks like Nigeria IPs is a great and safe place from a reputation pov
