LTE - O2 problem at different devices

[meyer360]

The problem exists with different devices, I tested motorola and samsung devices: motorola G14, G13, G8 and samsung xcover 4.

This is how the problem manifests itself: When restarting, 1 device out of 13 does not go online, there is an Internet connection via LTE, tested with Google Chrome. Traccar Client Status: Network error during transmission.

Here are some devicetests:

• disabling and reactivating mobile data doesn't help -restarting the device doesn't help at motorola devices, but with samsung -restarting traccar client doesn't help -restarting traccar Server does not solve (maybe idle)
• No problem with WiFi, only with LTE -airplane mode on/off, the device is immediately “online”.

Tested with: traccar hidden apk and Traccar client 7.4 from google store. I've testet older versions too. difference between xcover4 and motorola: xcover restart helps to go online

is there an idea? Today I would like to test changing to the network masts, maybe that will help.

Where do you see "Network error during transmission"? Please provide a screenshot.

Many thanks for your response. It's very strange, today I can't get the problem reproduced, maybe Telefonica had network problems for 2 weeks. I will test this again at the next opportunity.
