Credentials For Non-Proprietary Ports

I was wondering if anyone has configured their assets on non-proprietary ports using for example ssh instead of using 22 using 222?

On the credential report if creds are done for these I see a certainty of 1 but under authentication CREDENTIALS FAILED… why is that Logs even indicate a certainty of .90 not a 1? Engineers at Rapid7 told me it should work which it does but with some caveats maybe?

Any suggestions? I opened up a case and they told me 222 should work but like i said the credentials are contradicting themselves. Says failed, but its Cert of 1 but in logs it shows 90??
