Your system (which version with what CU are you using?) does not support TLS 1.2. Workarounds here: http://www.msdynamics.de/viewtopic.php?f=68&t=38242 . You might also consider an update: https://cloudblogs.microsoft.com/dynamics365/it/2018/12/06/how-to-get-earlier-versions-of-the-dynamics-nav-development-environment-to-work-with-tls-1-2/

Hello thank a lot for your help. My server is a WS2019 standart and NAVISION2015 CU2 (38798). But I never had any problems with the currency update except following the loss of an internet link. Can this error come from a port that has closed or? Cordially

No, the web service the ECB provides expects TLS 1.2 for the call of the client to be employed now, this change came on 23 September.

hello Thank's a lot .
Who is the official information about this change please ?
It's a bad news for my Old Navision not compatible with TLS 1.2
Best regards.

TLS 1.1 has been deprecated since March 2021, so the switch to TLS 1.2 was overdue.
