This happens when i restart NAV service in order to get jobqueue or NAS running but it seems it gets always freezes. Can't understand why and spent quite few hours looking for any bad configuration and online solutions but it without success.

This is having really because, i can't use webservices in other applications we have and or communicating with some sites for synchronization in this case odata. Soap works just fine.

Even after we migrated from Dynamics NAV 2016 to BC140 this worked...
Has someone had this problem?

Any help would be appreciated..


thanks in advance

    Hello,

    I believe we answered this yesterday. Best is to raise a support call via your partner or CSP to Microsoft.

    Thanks.
