HBO Max error code and can't authenticate

RokuDanny-R...I sent you a private message on this already but wanted to let you know publicly that HBO Max says it is a roku issue. For some reason roku isn't recognizing our device for hbo max. I am not even able to get to the sign in page for hbo max. And unfortunately there is no way to manually add a device to an hbo max account either. Any ideas????

Thanks for the post.

Try removing the channel from the Roku home screen by navigating to the channel tile, pressing the * key on your remote and choosing 'Remove channel'. Then restart your device from Settings>System>System restart. Once your player starts up again, add the channel back once more.

If you are still seeing the issue occur, you'll want to contact HBO Max support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves. 

You can reach HBO Max support here: https://help.hbomax.com/us/ContactUs

Thanks,
Danny

UserDanny-R…I’ve done that like 20 times and it never fixes the problem. I’ve also talked with HBO max customer support who says it is a Roku issue, although they tried to help me with suggestions that didn’t work either

Their HTTP request doesn't comply with HTTP standards and fails to pass my firewall's proxy:
