I have tried different browsers on desktop and laptop. Nothing will log me in the forums expect the phone I’m using. I can log into the database on any device.
I have never had this problem ever but I want to offer some suggestions.
Make sure you are 100% absolutely entering the exact same password on each device. I know this sounds like I am saying baby stuff but I used to be an I.T. guy and I have to say it.
This may do nothing, but have you tried changing your password or even resetting password like you forgot it. It may do nothing to help but it’s worth a try just to rule it out. Make it something super simple for now just to try it on the other devices.
I am 100% sure this is user error and I am not trying to offend you, I am just being honest and as others have said, it’s likely on your end. And it sounds like you are getting frustrated and it appears you’ve been trying to resolve it for some time and can be very frustrating. I see you’ve already went above and beyond trying to resolve it by reinstalling, formatting, buying new gear etc. You are making it harder than you need to and it shouldn’t as hard as you’re trying to make it, the resolution has to be something simple it’s just finding that resolution. So, I hope the few simple things I recommended help in some way.
