I am using Umbraco 7.4.0 (Assembly: 1.0.5885.31226) and have encountered a strange issue that started occurring without any recent changes to my setup.

Issue Description:

I am making a GET request to a specific resource, and the behavior follows a repeating pattern:

  • First request: :white_check_mark: Success
  • Second request: :white_check_mark: Success
  • Third request: :x: Fails with an error (500 Internal Server Error)
  • Fourth request: :white_check_mark: Success
  • Fifth request: :white_check_mark: Success
  • Sixth request: :x: Fails again
    … and the cycle continues.

Hi David, version 7 of Umbraco reached end of life back in September 2023 and version 7.4.0 would have been an early version of Umbraco 7 (maybe 8-9 years old). It would be very difficult for anyone to help you with the specific issue you’ve noticed due to its age.

However as a general suggestion you could go through upgrading to a later or latest v7 version and see if this fixes your problem. There are a number of steps and guides of how to do this, see the Version Specific Upgrades page, start with ‘7.4.0 to 7.6.0’ and work through. One other suggestion would be to update the .Net Framework to the latest version possible for the version of Umbraco you end up at.

I hope you find a solution!
