Obviously I tried that before asking for support.
It doesn't work:
"This account is currently locked out because a brute force attempt was detected. Please wait a few minutes and try again. Attempting to login again will only increase this delay. If you frequently experience this problem, we recommend having your username changed to something less generic."
I can access it from my work, which, once again: OBVIOUSLY, has a different IP address.. leading us to one thing: FIREWALL (cpHulk, csf deny list)...
IP (187.64.99.112)
Could you check this?
Thanks.
