oath refresh token - client network socket disconnected error

Hi - stuck, stuck, stuck on this step of calling via Postman for a refresh token. It pulls up the browser authenticate window, and says “authenticated” but Postman gives an error back “Client network socket disconnected before secure TLS connection was established”.

Checked out the typical google reported causes of this, and they don't seem to be the case. I have the app created, connected in the marketplace etc. But cannot fine any reason why I am getting this error. Tried it in multiple environments. Also tried running the “headless app” via Visual Studio, and getting a “bad request” when going that route.

I can run the API via the endpoint Blackbaud pages and can run an api with a bearer token - but of course that expires - so really need to get a refreshable token so that I can run this in an automated fashion.

Really hoping some kind soul has the solution out there - been banging my head against this for days. Thanks!

    @Arlette Slachmuylder - Sorry you are experiencing an issue getting a refresh token via Postman. Have you had any luck getting past the problem yet? Other than the usual disabling of “SSL Certificate Validation” in Postman or checking proxy settings, I'm not quite sure what else to try next. Are you connected to a VPN or other firewall that may be blocking the https request?

    Hi - no - absolutely no luck. I have tried the disabling of the ssl in Postman and checked proxy settings. I have tried doing it in our Azure environment vs. my laptop, I have tried it on a Mac rather than my windows computer and can find no way to get past this error. Is there anything in the setup or on the Blackbaud side that could be causing this problem? Thanks!

    Also - here are some screenshots, if that is helpful.

    Here is the error I get - AFTER a successful browser authentication

    Here are some of my postman setups - (I also tried the c# headless app, but that also gives me an error)

    Hi @Arlette Slachmuylder - sorry for the delay. A couple of us tried searching around logs for activity from your apps to the OAuth token endpoint. Nothing was found which would most likely point to a TLS connection issue. TLS 1.2 is required, as well as a few cipher suites. I don't expect that version of TLS would be a problem with recent versions of Postman.

    It would be interesting to know if you could access any of the following public URLs in Postman:

    …or if you have any problems accessing other https endpoints via Postman requests.

    @Michael Tims
    Thanks so much for getting back to me. I deleted everything out of Postman, cleared my browser cache, reset my pop ups and then populated everything back in and for some reason it now works. No clue why - but it now works like a charm.
