Getting SSL error with tls transport using self signed certificate

[nouman-zeb-snkeos]

I am getting this error while trying to move http input to https in fluentD.
My input config is the following

<source>
  @type http
  @label @*****
  port ****
  <transport tls>
    min_version TLS1_2
    max_version TLS1_3
    cert_path C:\**\**.pem
    private_key_path  C:\**\**-key.pem
    client_cert_auth false
  </transport>
</source>

The certificate are self signed.

I get the following error sporadically. When this occurs the logs are not ingested.
#0 unexpected error before accepting TLS connection by OpenSSL addr="127.0.0.1" host="127.0.0.1" port=**** error_class=OpenSSL::SSL::SSLError error="SSL_accept returned=1 errno=0 state=error: session id context uninitialized"

When I try to send data from postman I get the following error there.
Error: write EPROTO 4005837352:error:10000438:SSL routines:OPENSSL_internal:TLSV1_ALERT_INTERNAL_ERROR:../../third_party/boringssl/src/ssl/tls_record.cc:592:SSL alert number 80

I am not sure what I am missing in this case. Any help here would be appreciated.
