MongoDB connection issue because of Firewall

aaP_alicanselcuk · Dec 10, 2024

If I do not select "All" in the Source IP section for the port assigned to MongoDB and instead provide only the internal IP (127.0.0.1) or the server's IP, my applications running on Docker cannot access the database.

When I configure a firewall rule to allow access to the MongoDB port using internal or server IP, I encounter database access issues, receiving errors such as "Topology closed" or "Connection timeout." However, when I make the database port accessible from all IP addresses, there are no issues.

Is there a solution to fix this issue?

Hello, is the server IP you are using an internet address?
Can I use an intranet address?

We tried with both the server IP and the internal IP, but the result is the same, we still get the same error message and we cannot access.

It is recommended that you check whether the port is allowed to be accessed? Is the system firewall open?

The port permissions are correct and the firewall is open. There is no problem with the firewall working either, I do not have any problems with the rules I assigned to other ports except the port for mongodb.
