What devices you are using for this ? is it real time scenario or you testing it in eNSP ? have you provided "stp instance 1 root primary" and secondary commands on both side ? is "revision level" same on both side ? "region name" should be also same and it is case sensitive.

Please go through below link or paste the configuration to verify.
