Hello,
Could you please generate a troubleshoot file and attach it to this query? I'll leave instructions regarding how to generate the troubleshoot file as well as brief description about what it is below.
What's a troubleshoot file and how to generate it?
A Troubleshoot file contains the device's event logs, configuration files and other information useful for diagnostics. It can be downloaded from your device's WebUI, Troubleshoot page:
System → Administration → Troubleshoot
Best regards,
Tomas.
