Error Dolphin Connect

I have installed and configured the modules Dolphin Connect and OAuth2, 

But when I try to sign in with a site account on the other site I get the error: State parameter isn\'t matching

Why? thx

did you set up modules on the other site as well

 Do I have to install the same modules?

i could be mistaken - but i believe you need the Dolphin connect module installed in site number 2, and the Oauth module in site 1

the credentials from the Oauth module in site 1 are entered into the Dolphin Connect module on site 2

so - if a user is a member of site 1 and wants to join site 2 - they click the Dolphin Connect button on site 2 and it should pull in credentials from site 1.

Thanks, but I have reviewed the two modules and I think they are well configured.

Leave no record to see the error?

Do you need a boonex license for this module?
