    I am an IT professional and it takes a lot for me to admit defeat. My email had been working for ~3 days previously, and no changes had been made on my end that would cause this problem to happen. On my phone / other networks I can access my email via mydomain.com/webmail. When I try accessing it on my home network (via Chrome, Firefox, IE & Thunderbird) I get the log in is invalid (Sometimes it will work for a few minutes, but I cannot keep it going for long). I believe the port 2095 is blocked. I called comcast about getting it unblocked, but they said I do not have the credentials (I don't know who the owner of my internet is) to get it done by them. Here is a list of what I have tried:

    Directly wiring my desktop to the modem (same issue so I went back to the hard wiring through router like it usually is)
    Created firewall rule for TCP/UDP 2095 to unblock in Windows Firewall
    turned off routers firewall
    created a firewall for TCP/UDP in my routers configuration on 2095.
    Reset the router altogether back to default
    netsh advfirewall reset
    netsh winsock reset
    ipconfig /flushdns
    disabled avast! (my av)

    I tried it in safe mode and it worked for a few minutes, then back to the same error of "The login is invalid"

    I downloaded a program called simple port forwarding, and set up an opening for 2095, still not working
    canyouseeme.org/ times out when I try to access port 2095

    I just cannot figure this out. Any help is greatly appreciated.

    Sounds like your home IP may be blocked by cPHulk. If you don't have access to WHM, you might contact your Hosting Provider about this.


    GL!

    I have set up a VPN to connect through for the mean time which is a temporary work around, but I obviously, would like to get the root of the issue. I think you may be right that my IP was blocked, but it isn't just on my one computer, it is with any on this network.

    If the VPN worked for a bit, then stopped, it does sound like cPHulk or some other login failure blocker. You might look at your setup and make sure you don't have Outlook or something running that is generating a ton of password login failures. I see that all of the time.

    You have to find the offending program and stop it before you can solve the issue. Contact your host and ask them to tell you why you were blocked in the first place, that might tell you what kind of program is getting you blocked. If you are logging in without password failures, then I suspect that it is another program causing the issue. (Outlook, a port scanner...)

    That could be a possibility, maybe. I use Thunderbird, which automatically checks for new mail every 10 minutes. I did change the password on one of the accounts (previous to adding it to adding it to Thunderbird though) and used LastPass extension which might have had a bunch of failed log ins.

    I ran a few tests on a new VPN IP addressed and was successfully logging on and off the different accounts. Then, on purpose, I failed a log in on one of them 10 times and tried typing in the correct password, and it stopped working. I think we are getting to the bottom of this.

    Have you contacted your Hosting Provider? He can look at his log and tell you precisely whats happening here and if your IP is in his block list or not.
