The errors indicate that there is an impairment on your connection such as noise preventing technical messages not being receieved between your hub and VM's servers during Station Maintenance
You will need to contact VM for resolution, either by waiting here about a week until a VM Forum Team Member picks up the thread, or give them a call on 150 from a VM line or 0345 454 1111 for a quicker response. .
Thanks for taking the time to post on the community.
My apologies you are experiencing T3 time-outs.
When I checked your connection, there has been time-outs reported since the router has been online. However, as they are not real time, can you reboot the router for me please and I can check to see if they are continuing to rise. If so we can arrange for an engineer appointment to look into this for you.
If you can also reset the network log and re-post this for me please?
