    I had the same problem too. You must scan the upcoming articles once.

    1. Go to services.msc and check if your SQL server is running under which account. Ideally, make sure that the SQL computer and the SQL Server Service Agent are running the same

    2. in the Reflect database, you must follow the same step as in step 1. Enter the same credentials as on the required server. If this user is not considered to be present, create a new one on the servers with credentials.

    3. Now get the main server and add a login under “Security” -> “SQL Server Login”. Enter the system administrator as the public server roles. Optionally, you can add the same user to the mirror server.

    4. You are now mirroring the database principal. You didn’t have any mistakes there.

    In retrospect, it was obvious. When you send MIRRORING> CONFIGURE SECURITY WIZARD you will get a page explainingsome results. If you look at the nodes SQL1 and SQL2 this line looked like a key:

      On the primary instance of SQL1 serverListening port: ** Yes **From 5022Encryption: Mirror Period, SQL2Listening port: 5022Encryption: ** No **

    Having exhausted all of the above, I ended up with a replication environment option. We had SQL Web 2008 contributing to Server 2014 with master mirror configuration. In 2014, SQL Server was also used to configure AlwaysOn forensuring high availability of another database. Targets now have different names in sql 2010 and sql 2014.

    After getting the above error, it was determined that the encryption for 2008 can be RC4, and for 2014 only AES. As a result, it could not communicate with the SQL2014 endpoint. I changed the encryption to match SQL 2008 encryption which uses the following command and viola !!

    You cannot leave the mirroring emulation in bypass state, but you must leave it in this state to enable mirroring.

    1) Back up the original database and copy the situation to the server for mirroring.

    2) Save the log transaction and try again on the server intendedUsed for mirroring only.

    3) Select the recovery database in the entire MMC, find the backup in the recovery database and populate it with settings to leave it in an inoperative state without undoing transactions.

    4) Select “Recover” and select “Files”, then select “Log Files” and re-create the log file backup, which also includes a no recovery option that still does not work in Server 2008.

    5) Go to the original copy of the database and enable mirroring. For starters, you should really use an account with sysadmin rights to host the server and mirror conversations.

    I personally got rid of this issue and finally fixed it by collapsing and recreating the mirroring endpoints (SSMS -> Server Objects -> Endpoints -> Database Mirroring Data)

    Verification of service accounts. The SQL Server service account requires CONNECT permissions on partner endpoints.Checking ports.Make sure all instances have access to all other partners.Check the endpoints.

    In the Standard Edition, mirroring is used only in full protection mode; H. Additional synchronous mirror with indicatoractivation of electronic failover.

    With database mirroring, all join, update, and delete operations that exist on the underlying database are certainly just as fast. The mirror server instance must be running the same edition that is associated with SQL Server.
