ServiceBus error connecting to cluster SQL

Question

we have Service Bus newly installed in our enviornment. We do have errors below where we see SQL connection timed out. When we check on the SQL server, we don't see any failover or errors.

.NET 4.6.2 and TLS 1.0 is installed & enabled on both Service bus and SQL.

1) What's the configuration for Service Bus retries interval time and number of retries ?

2) Anyone had a similar issue ?
