Thank you so much for the advice!
I have tried the MTU check:
C:\Users\mille>ping -l 1373 -f 8.8.8.8
Pinging 8.8.8.8 with 1373 bytes of data:

Approximate round trip times in milli-seconds:
Minimum = 123ms, Maximum = 131ms, Average = 127ms
It appears that my minimum MTU may also be 1372, just like you showed.
It sounds like you are advising that I try lowering the MTU on the PanGP adapter from 1400 (the default) to something below 1372. I lowered it to 1300 by identifying the index of the GP adapter (idx 18 on my computer) and then setting the mtu for that adapter to 1300. I did this for ipv4 (shown) and ipv6.
C:\Windows\system32>netsh interface ipv4 show interfaces
Idx Met MTU State Name
--- ---------- ---------- ------------ ---------------------------
1 75 4294967295 connected Loopback Pseudo-Interface 1
11 70 1500 disconnected Wi-Fi
22 25 1500 connected Ethernet
17 25 1500 disconnected Local Area Connection* 1
7 25 1500 disconnected Local Area Connection* 2
18 1 1400 connected Ethernet 2
23 5000 1500 connected vEthernet (WSL)
C:\Windows\system32>netsh interface ipv4 set interface 18 mtu=1300
Ok.
However, the disconnect events still persist with the same debug message:

I will do my best to contact support -- I do not know if our institute has a support account, however.
Do you have any other suggestions regarding what might be causing this?
Thank you for your time,
Henry
