Hello,

Thank you for contacting Teltonika Networks Crowd support.

One thing to try in your case is to increase mobile interface MTU. Login to the your router via WebUI, then navigate to Network > Interfaces.  Edit mob1s1a1 interface settings. Switch to Advanced Settings tab. Enter 1500 in Override MTU field. Save & Apply settings

Otherwise, I would like you to attach a troubleshoot file to your question. Please, replicate the issue, then access router's WebUI, go to System -> Administration -> Troubleshoot section and download troubleshoot file from there.
