I have been working on this project for several months, and all of the sudden I cannot deploy the solution anymore. I am getting this error:

Error occurred in deployment step 'Recycle IIS Application Pool':  cannot 
connect to site https://blah.blah.blah. Make sure that this is a valid URL 
and the SharePoint site is running and so on...

I have done everything I have read to get this to work. Checked permissions, checked SQL access, reset IIS, recycled the App Pools, Check Central Admin and Site Collection Permissions, I run VS as an Admin, I mean everything; well obviouxly not everything or this would work right now.

I am working on a Claims based solution. I am not sure if this has something to do with it, or if it changed me somewhere on the farm. I can get to the farm through the URL and it is running just fine.

Edit: After checking the ULS logs, I am getting a Claims provider error on the custom solution's assembly, and I am also getting a security token request error. I am not sure what I did to get it to throw these errors, but for some reason SharePoint is rejecting my assembly for my solution.

Edit 2: Instead of carrying on in the comments, I will post here. I was able to deploy via powershell. When trying to access my WebApp I am getting Acces Denied which is expected right now, and another post in the near future. I am still puzzled as to why VS stopped deploying my solution and how my solution stripped my ability to launch from VS. Thanks for the help and suggestions!

  • are you deploying via powershell or directly from VS? what is your web application authentication confiuration? check the Event log and ULS log for more clue.

  • I am deploying via VS and this is a Farm level solution. I have been working between two WebApps. One is a simple Windows Authentication, the other is a Claims-Based WebApp where I have my custom Claims provider attached to it.

  • I did already. I also run as an admin in VS. I also made my account a server administrator as well, which is not a great idea but needed to try something, still no dice.

  • have you tried to deploy it using the powershell, i am thinking due to your custom cliam providers it is not recognizing the ur account...did you check the ULS logs and event logs?

1 Answer 1


I found that my issue was that my super user and super reader accounts needed to be reset. Once I removed and the re-added those accounts, everything started working as normal.
