Settings for external access

[hiro3500]

I really like using ZoneMinder.
I have two workstations at home, and ZoneMinder is running on both of them. One is version 1.36.35, and the other is 1.37.66.
Both are running smoothly locally, but only the 1.37.66 machine displays a black screen when accessing from outside the domain. The domain uses DDNS, with each ZoneMinder instance coexisting by changing the port for the same domain.
The port for the machine that cannot display video externally is the standard port 80.
This issue did not occur when both machines were running version 1.36.
Is there a special configuration required when accessing via the domain in version 1.37?
If there is a solution, please let me know.

By the way, accessing via a global IP address also yields the same result.

I forgot to mention that version 1.37 is running on Debian 12, and version 1.36 is running on Ubuntu 24.04.

Weird. Can you inspect the url in the img tag for the stream and post the differences?

Thank you for your prompt reply.
I have tried various things since then, and after opening the relevant UDP port in the router settings, it now works without any problems.
Open ports External Internal
Version 1.36.35 Ubuntu 24.04 Single port TCP　　　　 OK OK
Version 1.37.66 Debian 12 Multi-port TCP　　 NG OK
Version 1.37.66 Debian 12 Multi-port　　UDP and TCP OK OK

Does this mean that UDP also needs to be opened when setting up multi-port?
