Sometime after an upgrade it may be possible that requests from Service Market are not being sent to Process Manager , if that´s the case you can verify some things and see if that helps.
1. Make sure that you have the right web config and Azmanfile pointed out in Service Market configurator (see image) and restart the Process Manager Service after that.
OBS: It´s important to run Configurator as administrator when doing this change.
2.Make sure UserPrincipalName looks the same in web config and Active Directory.
Open up the web.config file and navigate to C:\inetpub\wwwroot\ServiceMarket(Accelerator) and open up web.config file. Search for <identity> and see if userPrincipalName for Process Manager account is the same here as in Active Directory.
It should look like below:
<identity>
<userPrincipalName value=”CORRECT UPN” />
</identity>
