Yes, OGG 18c does not support 126.96.36.199.x. Try to go to the latest version possible in the source side. In the target you can have either OGG 18c or 19c.
Below is the recommendation,
1. OGG versions should be same in both Source and Target.
2. OGG version in Target should be higher than the Source OGG version.
So, in your case, the Target OGG version is higher than the Source. So, it would not cause any problems. You can go ahead with the installation and configuration.
