Cannot log into Woodwork Forum but can log into Metal Work Forum

“Talked” to member Chambezio on the Metal work forum last night and he can’t log into this forum. This is his message.

”I have a regular "user" since 2009. My computer opens up with my Mail account Woodwork Forum and Metalwork Forum every day. I have not been able to access the Woodwork Forum for more than a month now, I only get Error 403.
My daughter is a Computer Tech for a living and she has run all sorts of tests and scans etc etc and her diagnosis is that the Woodwork Forum will not recognize my Account”

He also mentioned that he is on Satellite and maybe it’s a problem with his provider? If that’s the case, why can he get onto the Metal Work Forum?

Any help from the boffins would be appreciated.

Additional.
I’ll copy and paste all your suggestions to Chambezio on the Metal Work Forum.

ok, so I can't help directly, but here are the things I would do.

Incognito/ in-private browse to https://www.woodworkforums.com/ and no other URL. See if that works at all, or generates the 403 still; if not, then your IP is for some reason being blocked by the forum. The reason the MWF is different, is because it's a different instance of the forum software (even though it resolves to the same server IP address) and therefore may have separate IP block lists. If that works, but doing the same not in the in-private/incognito window I'd clear cookies related to the forum.

edit: also, for the forum team to look further, the IP address will most likely need to be shared with them so that a reason it's being blocked could be understood. it'd be a good idea to get that in prep.
