I reinstalled from scratch my (custom docker container) NxRM, using the same keystore.jks, file. I re-checked its password validity with keytool -list, and the password is valid.
The only difference between the new container and the old is that the old was running v3.69.x while this one is on 3.73.0-12.
Why is it now complaining of tampered keystore when keytool confirms its validity ?
