not streaming video whith OPT_USE_AUTH = true

[kimbilio]

I have a properly working zoneminder installation, with all functions working.
However when I enable "OPT_USE_AUTH" it does mostly as expected like logging on
and most function will still work like capturing and analizing and creating
alarm alerts. I can even view the alarm 'stills', but only video streaming, both
captured and live are no longer working.
The log will create a lot of repeated entries of:

However, the moment I disable "OPT_USE_AUTH" on the config page, all goes back to normal.

I am using zm 1.30 on Ubuntu 18.04 server
where I installed first a full LAMP installation, then followed the following guide:
https://wiki.zoneminder.com/Ubuntu_Serv ... e_easy_way

I can see it all starts with 'Unable to authenticate user zms.cpp' but what can I do about it?..

[rockedge]

try and set AUTH_RELAY to "none" when OPT_USE_AUTH is selected and enabled.....does the stream work?
do you have the AUTH_HASH_SECRET set to something? Set it and try setting the AUTH_RELAY back to "hashed"....does this work?

Thank you! That was exactly the solution.
I am a very happy person now
