Bug found? LTAP + ROS 7.8 + GPS issue

I’m afraid ROS 7.8 broke my GPS. I have an LTAP LTE which worked on ROS 6.x. This was going very well, until this weekend I decided to upgrade to ROS 7.8.

Since then my script no longer sends coordinates to my server. Nor do I get to see the GPS coordinates in Winbox.

Apart from the update, nothing has changed on the device. The GPS antenna is an external magnet antenna that has always worked fine and should definitely get a GPS lock at the moment.

Can someone please help me with this issue?
