The test program below shows an I/O error for Pike 8.1, and it shows Result "{\n" " "error": "invalid_grant",\n" " "error_description": "Invalid JWT: Token must be a short-lived token (60 minutes) and in a reasonable timeframe. Check your iat and exp values and use a clock with skew to account for clock differences between systems."\n" "}" (which is correct) for Pike 8.0.
