Since August 1st, the url of the web service changed, the application was running fine with the previous url, but with the new one, the application works for 1 user, the 2 other ones encounter this error message :
Could not establish trust relationship for the SSL/TLS secure channel with authority 'e-factura.sunat.gob.pe'
My project is a console one, in it, I use a certificate file to sign a xml file, the certificate is on a server, it's not installed on the certificate store. Moreover, to consume the web service, a wsse:security authentication is required. My app.config file is this one (I did hide the wsse:security credentials) :

I have no idea what to do to solve the problem, moreover, I can't consume the web service on my machine (the web service is used to sent real invoices to tax office). Thanks
