Routing-test OSPF problem in 2.9.12

If both routers are 2.9.12 with routing-test they can’t link using md5…

from log:
header error: authentication type mismatch

many times after Send Hello…

any solution ???

2.9.11 routing-test work fine
Thanks

If one is 2.9.11 routing-test and another 2.9.12 routing-test then it’s ok
