I was tried to connect the multiple environment in the Devops: Infrastructure.  But I am getting this below error. 

I am getting the server log like  ERROR com.appiancorp.connectedenvironments.logging.DevOpsInfrastructureAuditLogger - [ERROR, null, null, https://<other_site_subdomain>.appiancloud.com/suite , OUTGOING, null, null, null, null, null, null, null, null, null, URL did not return a valid public key: 

Please help me out to rectify this error.

Thanks in advance.
