Access to XXXX.3cx.cloud was denied

I keep getting:

Access to XXXX.3cx.cloud was denied​

You don't have authorization to view this page.


HTTP ERROR 403

It works from my cell phone, hotspot, remote site, but no longer works from one site on comcast. Comcast claims they are not blocking anything have waited over 48 hours and it does not clear. Any suggestions on why it look like IP has been blacklisted or blocked by 3CX?

Regarding your question, we can not block IP addresses from the total loss of access to 3cx SMB systems. If IP addresses are backlisted you will still be able to see the webclients login page, but not be able to log in.

I can get to 3cx, I can get to login page, however when I try to login it says Access was denied. Been 2 days of this... How do I get a blacklisted IP cleared?

 

[starojam]

the exact error when I try to login an individual extension is " An IP has been blacklisted"

 

[SteveITS]

One situation that can cause blocklisting is if a phone with old firmware has been set up as a router phone…it can’t do it properly so will repeatedly fail to connect until unplugged/deleted/factory reset.

Are you trying to login to https:XXXX.3cx.cloud or to https:XXXX.3cx.cloud/webclient ?

You need to use the https:XXXX.3cx.cloud/webclient link to be able to access your tenant. If you are using https:XXXX.3cx.cloud then you will get the same message every time.
