Hello @lisahanson

This "Connect timed out" error indicates that your network settings are not correct

[lisahanson]

Thank you @IvanGorshechnikov. I appreciate your feedback.

It ended up by something with my VPN connection to the server.

I'm having the same problem but I'm not running on a VPN.

I've been using DBeaver Community for several years.

I have several MySQL databases on a LAMP server that I've built using DBeaver.

A few days ago my Windows 11 machine rebooted over night. When I opened DBeaver all my Connection info in the Database Navigator was gone.

Since then I've verified that MySQL is alive and well on the server. I'm able to connect to the server via Putty and run MySQL. I can see all my DBs, query, create users, etc. But I can't connect from my laptop via DBeaver. I'm getting the following message:

Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
Connect timed out

If anyone can help me solve this mystery, I'd be happy to pay you $50 USD via Venmo

I created a test user and granted SELECT rights only to table photoID.

Server IP = 74.208.51.24
Port 3306
Database name = dennisdinius
Username = test
Password = TestP@ssword1

User test@% can login to MySQL and run the following query via Putty, but I'm unable to connect via DBeaver.

mysql> SELECT photoID FROM dPhoto WHERE PhotoCL='eclipse';
