hbomax app blocked

Firewall (Sophos XG Home) SFVH (SFOS 18.5.1 MR-1-Build326) 

I cannot get HBOmax app to launch on any of my Roku devices.  Roku TV,  Roku Ultra, Roku stick.   I am able to launch the HBOmax app on my android tv (although I've had other odd issues on it, ie Spanish instead of English).  I've recently discovered that my 2 amazon firesticks have no issue and launch and play HBOmax just fine.  

The error I receive using Roku's is:   HBO Max Application Error   Oops...there was a problem.  Sorry for the inconvenience!  Here's what happened:  *lost connection to the server * Error Code: 104

I've check the Current Activities > Live Connections  and I've notice SSL traffic (increases by 30k each time I try to launch the app).   I've contacted Roku and Hbomax and neither have been able to help me resolve the issue.   I believe it's something being blocked in the firewall.   

Anyone have any insight or suggestions for me?  TIA

  • Hi,

    what is your firewall rule and what ports have you allowed the devices to use?

    XG115W - v20 GA - Home

    XG on VM 8 - v20 GA

  • I just installed the firewall and it has only the default rules.  I'm vey new to this and I've not allowed ports for the device(s) to use.  I find it odd that only hbomax app won't work on the tv and roku devices.  All the other apps work fine. 

  • Probably trying to use upnp etc which are blocked. What does the logviewer show?

  • I had this same issue. In my case, I fixed it by disabling the http proxy server I had running on my router. I think it must have made HBO think I was doing something to avoid regional restrictions

  • Running firmware: SFOS 18.5.1 MR-1-Build326

    I had the same issue and resolved it using the following steps. It worked for me but certainly not what I want to do.  I'm not exactly sure what the root cause is but my suspicion is that they added more viewer tracking into the new Roku and/or HBOMAX app and the XG proxy interferes with that.

    I may tinker some more with the setting to add some security to the rule but at least it's working again.

    ***********************************************

    Created Hosts for all my Roku devices using their IP addresses

    Created a new Firewall rule LAN to WAN with the "Source networks and devices" selecting the Roku Hosts
    Inside of the Firewall rule, under "Web Filtering", set the "Web policy" to NONE.  
    Make sure no check boxes are checked.

    "Other security features" are set to NONE

    Created and linked a NAT rule to the firewall rule
    The NAT rule has "Translated source (SNAT)" set to MASQ  (When it was set to the default setting the HBOMAX app would still report a 104 error)

  • Thanks...this worked perfectly for me.

  • Thanks, I'll likely give this a try soon. I'd like to have some filtering on my Roku's however.  I've discovered that my firesticks have no issue so I've started to use them if I want to watch HBOmax.   I find it additionally odd that Firestick doesn't have a problem but all my Roku devices do.   

  • This tip gave me an idea... I tried changing the Proxy mode to 'Standard' (vs. 'Transparent') and it fixed my issue...
