Issue with Blue Iris alerts and thumbnails when using VPN instead of Port Forwarding

[Sardon]

Hello Blue Iris Community,

I'm encountering a perplexing issue with my Blue Iris setup and would greatly appreciate any advice or solutions you might have.

Issue Description:
When my system is set up to port forward on the router, everything works as expected. Specifically, when motion is detected, an alert along with a thumbnail of the motion is sent to my mobile phone. However, the problem arises when I disable port forwarding.

Detailed Scenario:

1. With port forwarding enabled on the router, motion detection alerts come with thumbnails to my phone.

2. To enhance security and avoid web port scans, I decided to disable port forwarding and access my cameras via a VPN tunnel into my LAN.

3. After this change, although the motion alerts are still sent to my phone, they arrive without the thumbnails.

Question:
Is there a way to configure Blue Iris so that it still sends thumbnails with port forwarding disabled with alerts when accessed via a VPN ? I'm really stumped as to what is causing this issue.

I would be immensely grateful for any insights, suggestions, or guidance on this matter. Has anyone else experienced a similar issue? How did you resolve it?

Thank you in advance for your time and help!

Best regards,
SN

You are not alone, I use Tailscale and get exactly the same. So if I’m at home the alert comes through with the thumbnail, if I’m away like you I get the alert but no thumbnail.

I spent sometime looking into this but never really found a solution.
