NBXplorer stuck

See original GitHub issue

from @JurGi7: I have the same problem, after updating to 1.7.1 I often see the message “Waiting for Chain Sync”. Furthermore, I see on the BTCPayserver interface for two weeks “Your Node are synching”. In the meantime, however, it works and seems to be synchronous. What can I do?

@openoms: check if sudo systemctl status nbxplorer and sudo journalctl -n10 -u nbxplorer has any errors. Restart the services with: sudo systemctl restart nbxplorer sudo systemctl restart btcpayserver

from @JurGi7: Hi openoms, thank you for your answer. Here are the outputs on the commands. nbxplorer and btcpay restarted. Jurgi
