Looking for suggestions / ideas on this one.
Wrote custom code to upload / export Excel based data into Microsoft CRM. The code has been running for years now with no issues.
Recently (about a week) whenever the user's try to upload/export data into CRM they get the following error:
Error retrieving opportunity list: The HTTP service located at https://fs.yourdomain.com/adfs/service/trust/13/usernamemixed is unavailable. This could be because the service is too busy or because no endpoint was found listening at the specified address. Please ensure that the address is correct and try accessing the service again later.
If we reboot the CRM server, everything is restored and they can now upload their information. Until the next day when they start work/try again. The pattern repeats.
Note: at all times (when they get the error when they don't) user can continue to log into CRM using their browser. The issue appears to be only related to the custom coding.
Reading a few postings I can confirm. The integration user account is active and the password has not expired/unchanged.
Any thoughts / suggestions / ideas?
Thank you for your suggestion. ADFS is hosted by a 3rd party so we've opened a ticket. If your suggestions helps. Will let you know / mark as answer
Hello Michael,
This issue has origins from the ADFS endpoint.
/adfs/services/trust/13/usernamemixed ::
As per the ADFS security documentation, this endpoint gets mainly used for Exchange Online with Office clients older than Office 2013 May 2015 update.

Please check with your ADFS team if they recently made any changes on to the ADFS. Probably looking into the ADFS admin event viewer logs during this time of the incident would give more insights on why this ADFS HTTP web service endpoint went down.
Please mark my comment as answered if this helps.
Thanks,
Saurabh
