Getting many OnConnectionFail 1040 on mobile client

Options
Hi I am getting a lot of OnConnectionFail 1040 timeouts on mobile clients.
This never seems to happen when the application is running in the Unity editor on the same network.

After checking out
https://doc.photonengine.com/en-us/pun/current/reference/analyzing-disconnects
I am running the following code before ConnectUsingSettings() to no avail:

PhotonNetwork.QuickResends = 3; PhotonNetwork.MaxResendsBeforeDisconnect = 7; PhotonNetwork.networkingPeer.DisconnectTimeout = 60 * 1000; PhotonNetwork.BackgroundTimeout = 60 * 5;

What could be causing many 1040 errors on mobile phone clients that don't happen in the desktop Unity editor?

Where are Photon's logs on iOS kept?

I am using the On Premise server at our office. Is there a setting that can be made here to be more lenient about timing out iOS clients?

Regards
