Hi,
Thank you for posting in Microsoft Q&A forum.
1,Where do you see these errors? Is the SMS_REST_PROVIDER shown green under Monitoring\System Status\Component Status?
2,Please reboot of the server to have a try. If possible, we can also try a site reset and see if it repairs the provider.
3,Message ID 11610 usually occurs when there is a trust failure: "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel." This error is due to the fact that the connection to the administration service is being made over an SSL/TLS secure channel, but the certificate presented by the server while establishing the connection is not trusted by the client. The SSL/TLS certificate presented by the server could be invalid, self-signed or the certificate chain is incomplete.
On the other hand, Message ID 11615 occurs due to a PKI certificate issue while connecting to the administration service. It could mean that there is a problem with the PKI certificate being used.
Based on the information you have provided, I would suggest the following troubleshooting steps:
Check the validity of your SSL/TLS certificate and ensure that it is trusted by the client.
Check for the completeness of the certificate chain.
Check the validity of the PKI certificate being used.
Check the time and date on your server and ensure that they are correct.

Thanks for your time. Have a nice day!
