That means that you need to import the same PEM file containing the leaf certificate and private key to each mid server key store. They can share the CA certificate record and the sys_user_certificate record on the instance side. You need to ensure that each MID server service has a unique service name so they do not conflict. If running into issues, as a next step, we would recommend correcting the mid.ssl.bootstrap.default.check_cert_chain setting and carefully follow the instructions in [code]≤a href='/kb? id=kb_article_view&sysparm_article=KB1116112' target="_blank">KB1116112- MID Server Mutual Authentications/a-[/code].
