    Hi All

    I have been getting this error when trying to access my whm sites.
    Code:
    This site can’t be reached
    The webpage at https://mail3.example.com:2087/ might be temporarily down or it may have moved permanently to a new web address.
    
    ERR_TUNNEL_CONNECTION_FAILED
    
    In both Chrome and Opera but not in Firefox.

    It appears to be a proxy issue, but why is it not affecting Firefox on the same computer ?

    Any pointers appreciated. I am assuming some sort of proxy issue, but there is not specific on the desktop configuration for any of the computers on my home network. All are affected the same.

    It must relate to my firewall, but still why is Firefox working ?

    Thanks.

    Hello @thowden,

    Are you using any firewall rules at the router level? One way to rule out your router configuration is to connect an affected workstation directly to the modem via an Ethernet cable to rule out the router as the source of the issue.

    Thank you.
