We apologize for the inconvenience caused.
As we understand that, you are encountering an issue where your Azure CosmosDB instance is reporting a wire version mismatch. Even though you have upgraded to server version 7.0, the error message indicates that the server at 10.3.2.5:10255 is still reporting wire version 6, which is incompatible with your current version of libmongoc.
Here are a few steps you can take to troubleshoot this issue:
- Verify the Upgrade: Double-check that the upgrade to version 7.0 was successful and that all nodes in your cluster are running the correct version. Sometimes, individual nodes might not upgrade properly. Double-check the connection string (URI) your backend is using. It should match the one from the Azure Portal.
- Restart the Service: Restart your Azure CosmosDB instance to ensure that all changes take effect. Try clearing any DNS cache on your application host.
- Check Connection Strings: Ensure that your application is connecting to the correct server and port. There might be a configuration issue causing it to connect to an older instance. If your connection uses a private link, ensure it's correctly configured.
- Firewall or Network Security Group (NSG) Rules: If you are connecting from a private network or VPN, verify that the correct Azure Private Endpoint or Virtual Network settings are used.
- Update libmongoc: Make sure that you are using the latest version of libmongoc that supports MongoDB 4.0 or higher.

Got following error:Caused by: org.springframework.data.mongodb.UncategorizedMongoDbException: Server at cdb-ms-prod-eastus1-fe13.documents.azure.com:10255 reports wire version 6, but this version of the driver requires at least 7 (MongoDB 3.6).
and here is additional log for you to analyze potential issues:
