Shelly TRV 2.1.8 - Update problem

Hi, I can´t figure out how to update the Shelly TRV to version 2.1.8 from version 2.1.7.

I tried to factory reset and update by using the cloud app, the web interface and doing an manual update:
http://*HiddenIP*/ota?url=http://archive.shelly-tools.de/version/v2.1.8/SHTRV-01.zip

But it always brings me back to 2.1.7 after it has done an reboot and then asks for the 2.1.8 again in the cloud app and web interface.

My other Shelly units in the house update fine and I can see that they get past the firewall no problem.

Current version: 20220720-094550/v2.1.7@f9b0e22f

New version: 20220811-152343/v2.1.8@5afc928c

Im stuck. What would you suggest?

Solved!

I had to run this line in my browser and the Shelly TRV finally updated after 2 tries! (I have been banging my head against a wall for hours till I found this address.)

http://0.0.0.0/ota?url=http:/…RV-01_build.gbl
(Change 0.0.0.0 to the TRV device IP)

Link still works for me.
Remove xxx and type the correct IP that the device have. Should look not the same but similar to this: http://192.168.1.123/ota?url=http:/…RV-01_build.gbl
(Else you will get an page not found if there is no device on the IP.)

Check your device IP on your router if it's connected there if you cant see it and it's IP on your phone
