Help Getting UHF DVR Functionality Working with ZusOTT

Hi everyone,

I’m hoping someone familiar with ZusOTT and UHF Server can help me troubleshoot an issue.

I have a ZusOTT Strong 8K IPTV subscription that allows one concurrent connection. I’m using UHF on my iPad and Apple TV, and recently installed UHF Server on my Intel iMac to enable DVR recording.

My setup:
IPTV provider: ZusOTT (Strong 8K)
Subscription: 1 concurrent connection
IPTV player: UHF
DVR: UHF Server running through Docker on an iMac
Devices: iPad and Apple TV

Using the provider’s VPN DNS URL rather than the standard public DNS

The problem:
Live IPTV streaming works properly on my iPad using the provider’s VPN DNS URL. However, when I attempt to record through UHF Server, the recording fails with a 403 Forbidden error. I’ve checked the server logs and confirmed that the server is running and responding to requests. Importantly, I wasn’t watching any live channels on my iPad or Apple TV when attempting the recording. The iPad was off, so I don’t believe I was exceeding my one-connection subscription limit.

My questions:
Does ZusOTT support DVR recording through UHF Server?
Could the 403 Forbidden error be caused by restrictions on server-based recording, even when no other streams are active?
Has anyone successfully configured UHF Server to record from ZusOTT using a single-connection subscription?
Are there specific settings in UHF Server or ZusOTT that I should adjust?

I’d really appreciate any suggestions from anyone who has encountered something similar.

Thanks in advance!
