The error message "A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later"
in Magento 2 can occur for a variety of reasons. Some possible causes include:
- Server-side issues: This error can occur if there is a problem with
the server, such as a lack of resources, a configuration issue, or a
software bug.
- Database connectivity issues: If there is a problem connecting to
the database, this error can occur.
- Incorrect file permissions: If the file permissions on the server
are set incorrectly, Magento may not be able to access the necessary
files and this error will occur.
- Caching issues: If there is an issue with caching, such as outdated
cache files or a problem with the caching configuration, this error
can occur.
- Extension conflicts: If there is a conflict between Magento
extensions, this error can occur.
- Custom code conflicts: If there is a conflict with custom code, this
error can occur.
- Server overload: High traffic can overload the server and cause this
error.
It is best to check the server logs, database logs, and Magento logs to get more insights on the issue and determine the exact cause of the problem, then take the necessary steps to resolve it. Also, if you have recently made any changes to the server, site or extension, you can try to revert those changes, that might help you resolve the problem.
Let me know if any query.
THANKS.
