Symptoms:
For some users, login to internal node gets redirected to external node.
Cause:
In $IAS_ORACLE_HOME/instances/EBS_web_SID_OHS1/config/OHS/EBS_web_SID/mod_wl_ohs.conf and apps.conf files, the cluster includes the external node external.domain.com.
Solution:
To fix this issue, make the following changes to the run file system of the internal node:
Remove any reference to external.domain.com from both the files i.e. mod_wl_ohs.conf and apps.conf.
