Hello all,

we work with asp net 4,5 and have a web site in http normal ..all work fine.

Due to some reason of security we need to pass all url in https.

Our IT Network team has place a certificate inside the computer (server host IIS) and now i know i need to bind the certificate to the app pool with the port 443 -> https

But ; i would like to know if i need to restart IIS after have place the correct binding (certificate + https) ?

No you don't have to restart IIS for a binding to take affect.  Have you tried?  Are you having a problem?

This error happens when there is another service running on port 443.   The community cannot see your IIS managers and look around.  It's up to you manage the applications configuration and ports.

In later versions of IIS 8+ you can specify the host name and check "Require Server Name Identification" when creating an application binding.

Hello mgebhard,

pfff it's complicated when guys have not knowledge ! 

that's strange because in IIS i can't see web app who used this port -> 443 !

But after search we have on this machine a tool who has his own web server  who used this port 443

Could you confirm if i fill the field -> dns and check the checkbox no conflict will be occured ?

thanks a lot

that can be ok

thanks

I cannot answer this question accurately.  I would try.  If you get the same error then look into fixing the configuration for the service running on port 443.
