Hello,

i have big trouble with 2 of my PCs to get connected to the GPUGRID Servers.
At the beginning (2 or 3 days ago) the connection was slow and sometimes ended in timeout. But reload did help.
Now GPUgrid ist completely dead. The Website is unreachable, the WUs wont get uploaded.

But a ping to www.gpugrid.net works, only about 10% packet loss.
On the 3rd PC everything is fine.

All 3 PCs are connected to the same router.
The not working PCs have Ubuntu16LTS and the working PC has Ubuntu 18LTS.

The rest of the internet is working also fine.

Any ideas why 2 of my PCs cant talk any more with GPUGRID?
Reboot didnt help.

One thing that might be one piece of the problem: i cloned the SSD of one PC somedays ago and used the clone in the other PC. But the PCs got different names and the IDs in the project are also different. Und at the beginning that was no problem. Both PCs got work and delivered the results. And other projects can communicate with their servers without problems.

Traceroute looks quite similar.

PS: i posted this problem already in the gpugrid forum - but the access to the forum is now also not possible and maybe its a general topic and has been seen on other projects also.

Problem was solved.
I put the SSD of one blocked PC in tha last working PC. There i could upload the data.
In the same time i updated/refreshed on the blocked PC #2 and magically there also the upload started.
In the end all WUs are uploaded.

Big underlined note for me: GPUgrid is not amused about cloning an SSD in another PC.

I have intermittent problems with GPUGrid all the time. It seems to be worse in the U.S., but maybe happens sometimes in Europe also.
