Noda is catching up with the network block by block, and that's all. Although your node is visible in the dashboard.

Hi ZloyMyshok

Did this happen on starting the node, or after a loss of connectivity?
If it happened after a loss of connectivity, try to restart your node and Docker.

If not, we might need to see the full log (the log can be generated using the tool concordium-node-retrieve-logs.exe).

Kind regards,
Emil, Concordium Support

Communication is not lost. Reboot doesn't help. The error in the testnet -support branch has appeared more than once, but everyone ignores it.

Hi @ZloyMyshok, thanks for the log snippet.

Just FYI, we are not ignoring it, as you stated. We've collected several reports from different channels and asked users to provide us with more info like log files and scenario descriptions. We could not reproduce the issue internally on our own nodes in our first trials. But we are still investigating.

[buivando130898]

a lot of people have the same problem. What is the solution

[concordium-cl]

We figured it out now. I have described it in #70. Please have a look @ZloyMyshok and let me know, if it works for you.

And since you asked so nicely, please have a look there as well @buivando130898.

[ZloyMyshok]

Hi ZloyMyshok

Did this happen on starting the node, or after a loss of connectivity?
If it happened after a loss of connectivity, try to restart your node and Docker.

If not, we might need to see the full log (the log can be generated using the tool concordium-node-retrieve-logs.exe).

Kind regards,
Emil, Concordium Support

the concordium-node-retrieve-logs.exe tool outputs a file that is too large in memory and cannot be uploaded. if only concordium-node-retrieve-minified_logs.exe but it is uninformative.

[ZloyMyshok]

Yes it really works! But I think that this is not correct. Node cannot support the latest Docker updates on Windows !!!

[gilescope]

It would have been really helpful for the website to point this out.
