Last-Modified header is invalid: api.swaggerhub.com

Hi szepeviktor 

You are right !!

The "Last-Modified" header you've encountered appears to be invalid.

The header specifies UTC (Coordinated Universal Time) instead of GMT (Greenwich Mean Time).

While they are very similar, some tools might expect the traditional GMT format.

Ø  Try with this format and this should work for you

Ø  Last-Modified: <day-name>, <day> <month> <year> <hour>:<minute>:<second> GMT

Upon trying this - If the API or data retrieval from SwaggerHub is functioning normally, you can likely disregard this warning. The time difference between UTC and GMT is usually minor.

If you're experiencing issues fetching data or using the API due to this error, consider reporting it to SwaggerHub support.

Hope this helps - Happy to help further!!
Thank you very much and have a great one!

Warm regards
