SOAP API stopped working - [ISS.0088.9139] Output parameters do not conform to targetOutputSignature errorCode=VV-002

We have had an interface between SFDC and our company for well over a year. All of a sudden, updates to SFDC are erroring out with:
Environment: %Environment%
Server: %Server%
Transaction Type: %TransactionType%
Error Message: [ISS.0088.9139] Output parameters do not conform to targetOutputSignature:
                errorCode=VV-002
                pathName=/fault/detail/fns:UnexpectedErrorFault/fns:upgradeURL
                errorMessage=[ISC.0082.9026] Undefined Object found
 
                errorCode=VV-002
                pathName=/fault/detail/fns:UnexpectedErrorFault/fns:upgradeMessage
                errorMessage=[ISC.0082.9026] Undefined Object found

No known chages to the environment. Login by the interface user is successful.

We have similar problem. We are using SOAP address https://www.salesforce.com/services/Soap/c/15.0 and trying logging on it throws exception

AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: org.xml.sax.SAXException: Invalid element in com.sforce.soap.enterprise.fault.UnexpectedErrorFault - upgradeURL

It worked for many years before and stopped October 21th. It's probably because of disable TLS 1.0, but we've changed our service settings and still no success. Is there necessary to use different entry point (change SF API url)? Thanks.
