Unable to Login to Dynamics CRM

Posted on by 510

Hey guys.

I'm facing this issue: LastCrmError = "Unable to Login to Dynamics CRMOrganizationServiceProxy is null" while trying to login into CRM from any code, like console application or Web Service. Everything was working in one day and suddenly we started to face this problem.

Any help?

    I did not see the url inside your post, i was reading from my phone so probably the URL was broken.

    I was reading the article and now make sense, thank you Pawel.

    It's not strange at all if you follow the latest requirements:

    I posted it at the beginning of this topic, but you ignored it...

    Yeah. I've downloaded 30 minutes ago and now it's working.

    It's weird that the 8.2 version Plugin registration stopped working from nothing.

    Thank you anyway.

    Are you using version 9.0.0.7? You have to be using latest version of PRT

    Are you still getting this. This is an email that I got from Microsoft last night:

    Starting on January 04, 2018, 2:12 AM UTC, we detected a problem with Dynamics 365. Your users might not be able to sign in right now or they might have trouble using some features.

    For more information and status updates, please see the Service Health page in Office 365.

    Thanks for your patience while we sort this out.

    Yes, I see.

    But the weird thing is that I'm able to connect using plugin registration into one client Environment and the other one I don't.
