Hello,

One customer uses Web service of PcVue 11.2 and they met this issue. Do you know how to do? thanks.

Access to XMLHttpRequest at 'http://192.168.254.186/SessionContext/SessionContext.asmx?op=OpenSession&{UserName:%27user1%27,Password:%27123456%27}' from origin 'http://localhost:8098' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

BR,
Mark

Hi Mark,

I guess the issue is not directly on PcVue / Web* side but system policy.
The error message is barely the same in the following case:

Maybe the customer will need to switch to https.
Has he tried locally with localhost or/and 127.0.0.1?

BR
Edouard
