Users with similar devices on the network are faring no better than you, Jarno. See bug 1821932 and bug 1811504. Thank you for trying.

From the extensive information you and others have provided (all the logs are very similar), I am inclined to see the root cause as being down to some interaction with the ESCL part of the plugin.
