And another question - in my wallet I have the inscription "Node status: Alone on the world" - does the wallet not see the network?
Yes. "Aloen on the world" means you're not connected to PascalCoin blockchain so you cannot check/mine
The question is why this is happening. Yesterday I updated the wallet itself to the latest version, I launch it - synchronization takes place, for a while everything works fine - you can see that the chain is synchronized, and then it goes back to the "Alone on the world" statute. At the same time, I do not change anything, there is traffic, everything works
The information you provide is not enough to diagnose the problem. The screenshot does not show which version of pascalcoin you are using.
I know this much, if you mean with "latest version" pulling code from git from most recent commit then pascalcoin might not work because currently the absolute latest version seems buggy.
If you are using a "release" version then pascalcoin should work.
If release version not working then in that case check firewall settings, restart pascalcoin or post some debug logs here perhaps then we can take a look at it.
(Examine the GUI until you find the debug log option, there should be a checkbox somewhere, though it seems you are using a deamon... is the pascalcoin wallet/gui working on your system ?)
(Could also be a problem with miner code, maybe it was not updated to work with latest version of pascal coin deamon ? this just speculation for now)
What you could try is fall back to a previous version that was working. Let us know if this works for you.
Also let us know which version did and which version didn't work.
1. Version 5.3.3
2. No changes in the server environment (firewall, permissions, etc.) have been changed
3. Prior to that, the previous version of the Pascal wallet worked without interruption for several months.
