The verb “ try” here means “to call” as the context is “Attempting a Telegram call”. The verb” تلاش کردن” is a literal translation of the verb “try” which means “to attempt” in Persian and is not an accurate equivalent for “try” in this context.

Both sentences are imperative so the word "check" has not been translated grammatically correct in the applied translation. In my suggestion, since translated verbs are partially parallel I have removed the word "کنید" after "بررسی" for better fluency.
