Guess what? I'm able to login properly from my home network!
IP address hasn't changed on my side. My cable provider had suggested to power off my modem for 24+ hours in order to try and get a new IP address, but I couldn't find any time for that. Hope it sticks this time. I'm even afraid to hit the 'Post' button and for every F5 after that. Becoming a bit paranoid lol
I've checked for your issue yesterday
And Disabled a ban matched to your description [ Spam. Multi acc.]
but not related to your IP.
+
checked you with the spam system and your acc. turning in red immediately,
means its flagged by the spam system and always blocks you.
I override it and approve your login, to do not chase you again in the future
So I'm hoping either of them or both to have some effect over your issue.
However, I see your IP is flagged as spam generally to the world database:

else you will have the same problems on a different forums too,
soon or later.
