Recently we have started receiving below error in Event Viewer. We googled for it but as per links we get it is to to do with SharePoint Security Token Service.
An operation failed because the following certificate has validation errors:\n\nSubject Name: CN=*.yahoo.com, O=Yahoo! Inc., L=Sunnyvale, S=CA, C=US\nIssuer Name: CN=DigiCert SHA2 High Assurance Server CA, OU=www.digicert.com, O=DigiCert Inc, C=US\nThumbprint: 071211108F3C32CD7D3F9A5E94AC8C3EC3BF2FD7\n\nErrors:\n\n The root of the certificate chain is not a trusted root authority..
Any ideas for this?
Hi,
You need to export every certificate in the certificate path, and add it to managed trusts in Central Administration or by using powershell like so. https://technet.microsoft.com/en-us/library/ff607586.aspx
Please let me know if this helps.
Hi Beau, I had come to know about my query if issue starting showing later through another forum ‘https://sharepoint.stackexchange.com/questions/221280/yahoo-certificate-error-yahoo-web-service’ However sorry for asking this, I don’t know how to export the required certificate. Below are the URLs i can see in code; http://finance.yahoo.com/currency-converter and http://finance.yahoo.com/d/quotes.csv?{0}&f=sl1d1t1ba&e=.csv
Hi Beau, Thank you for your response. However, it is bit strange, the service was working correctly until few days back (Which means the required certificate was there). And i haven’t removed any certificates as well! Did it happened due to AV running on server…? Kindly provide your inputs.
