HI UR-2878,
“caused by third-party infrastructure returning an incorrect certificate in redirection scenarios.”
“the client return a 0x907 error code when connecting to a server endpoint with a certificate that had a Remote Desktop Authentication EKU property of 1.3.6.1.4.1.311.54.1.2”
“the client to return a 0x907 error code when processing a server authentication certificate with a validity lifetime of over 825 days”
I see the same issue also happen on Remote desktop for Mac OS, it has been solved, but I haven't found workaround for ios device, so please use the previous version of RD client again and post this issue in below forum then wait for the next new version of RD client publish. It will be solved soon. Thanks for your cooperation.
