Hey Guys,

I have been facing issue integrating partner SOAP web service:

• Login call goes through successfully, so I could get session ID and URL
• When I make the second request to perform the specific operation I get an error: No operation available for request {http://soap.sforce.com/schemas/class/ws_Application_BLL_PF}onboard_Sub_Merchant

I have been changing URL, modifying the header, even WSDL file itself, nothing seems to be working, is there anything that I can try to make it work?

 After going to log into salesforce forum I see this error message.
Problem Logging In
We can’t log you in because of the following error.
REGISTRATION_HANDLER_ERROR: ACCESS_DENIE​D_playful-goat-477032-dev-ed.my.salesforce.com
I have seleted single sign on rule but this still happens. Anybody know how to deal with? I have also some issue with trailhead than I can´t finish so I hope I can post it here. No other choice.
