I am also the admin. I found this. I am not sure why it is 401 unauthorized.
The following query failed: FilterOwssvr2A
(User: domain\user, Form Name: name, IP: , Connection Target: ,
Request: AllItems.aspx&DefaultItemOpen=1, Form ID: urn:schemas-microsoft-com:office:infopath: :-myXSD-2011-09-15T18-54-35
Type: DataAdapterException, Exception Message: The form cannot run the specified query.
The remote server returned an error: (401) Unauthorized.)
I will say before this error I got this until I exported the cert and imported it into Central Admin:
An operation failed because the following certificate has validation errors:\n\nSubject Name: CN=portal..com, OU=Terms of use at www.verisign.com/rpa (c)05, OU=Admin, O="",C=US\nIssuer Name: CN=VeriSign Class 3 Secure Server CA - G3, OU=Terms of use at https://www.verisign.com/rpa (c)10, OU=VeriSign Trust Network, O="VeriSign, Inc.", C=US\nThumbprint: \n\nErrors:\n\n The root of the certificate chain is not a trusted root authority..
After that error was gone but now I am unathorized
