Authentication to remote instance failed on PROD after turning on MFA setup

[Jatinder_singh]

Hi,

I just turned on MFA on QA and tried to migrate source changes to PROD and got this error message " Authentication to remote instance failed. The error reported was "Method failed: (https://qa.service-now.com/sys_update_set.do?SOAP&displayvalue=all&redirectSupported=true)HTTP/1.1 401 Unauthorized with code: 401". Check saved username and password." 

Both instances have the same security patches. MFA is not on PROD it is only in QA. If I turned it off on QA there been no issue to update sources. 

Thanks

Hi @CharanjitSingh 

This issue resolved for me by providing correct user ID and password, please try giving exact user ID from your insurance

Hi @Pavan kumar jog ,
I have also resolved this issue by disabling the MFA in the source instance. As MFA is not supported yet for Remote instance connection

Hi @CharanjitSingh ,
it is not recommended to disable MFA. Did you try using an account with web service access only flag enabled?

I recommend creating a service account on the source instance w/ Web service access only = true, and grant it the admin role.  This resolved the issue w/ MFA preventing the authentication over SOAP when using an interactive user.
