WAN connection INTERNET_R_UMTS1:IPv4 disconnected every midnight

[ShoA]

Hi,

I'm currently having an issue where in the past 3-4 days my router has decided to disconnect every midnight. This wasn't an issue for the past year and a half. 

As far as I'm aware nothing has changed and the configuration for my router (HUAWEI CPE PRO2) has remained untouched. It seems like a change has been triggered from EE's end. 

Below are logs for the past 2 days seen, could someone please assist or clarify if/why EE is now forcing a disconnect every midnight? 

I actually had a much bigger log which covered the past few days, I unfortunately no longer have this. It's definitely been happening for the past 3-4 days, every midnight. Although the log below suggests a disconnect had occurred at 13:52:50, that was the only anomaly across the past few days.

According to your Logs, its Disconnecting then reconnecting again straight away, but I've noticed you have a Time Setting Error on your Logs,?

Look at - Thu Mar 23 13:53:01 2023,time zone:GMT+01:00

Then look at - Fri Mar 24 00:04:12 2023,time zone:GMT+00:00

This Error could or may cause a Router Restart, check your Time Server within Settings are correct, from memory there are 2 Settings, one as a Primary Server, second as a Back Up, these Setting ideally need to be from the same Time Region which could be, or is, deferent from Home Time Settings ie, London, Lisbon + or no + GMT.

I normally set any Time Server Settings to NASA.Gov.

Hi mate,

Thank you for your message. I had a look at the timer server and currently primary is set to ntp.nasa.gov and secondary is set to time.nist.gov. Does that look fine?

I've managed to pull some further logs and unfortunately you can see I've been hit with another disconnect. I had a look at the IP conflict for those particular devices. Within the DHCP settings I manually assigned IP addresses to those devices and that made no difference, still getting IP conflict as well as disconnects around midnight.

Hi, 

Have you figured out what has happened here? 

I have almost the same issue here, I have a Huawei cpe pro as a receiver on bridge mode connecting to an ASUS router for router and wifi.

Randomly around midnight(0:00 -0:05), I saw "WAN connection INTERNET_R_UMTS1:IPv4 disconnected" and many "Sync time failed from BBOU" before and after this message. Then the Internet dropped until I need to unplug and re-plug the Huawei router.

Not sure whether it's EE renewing all the ips given out or some other things happened.
