LSN mismatch error in Log Shipping

LSN mismatch is a common issue which happens in Log Shipping and because of which the Log Shipping goes out of sync.
When you check the history, you will find messages like below

Msg 4305, Level 16, State 1, Line 1 The log in this backup set begins at LSN 36000000048400001, which is too recent to apply to the database. An earlier log backup that includes LSN 20000000022100001 can be restored. Msg 3013, Level 16, State 1, Line 1 RESTORE LOG is terminating abnormally.
