TLS connection Alert

I recently updated to v0.58.1, and I'm frequently getting a "Not Found" page when connecting to external links using TLSv1.2.
I confirmed using Wireshark that an EncryptedAlert(21) is occurring when connecting to external links using TLS.
I'm not sure when the error resolves, but sometimes it appears over time. Similarly, sometimes it doesn't appear even after some time has passed.
I know that the server on which Metabase is implemented returns an EncryptedAlert(21) to the client, but I don't know what the cause is.
Could anyone please help?
Thank you.

[Additional Information] Metabase itself is started by registering the jar file with systemd. The database was migrated from H2 to PostgreSQL in the previous upgrade.
