Hi,

1)

       Switching to Chrome and not experiencing the issue may indicate browser-specific settings, such as caching or cookie management, are influencing the behavior. To troubleshoot, consider the following steps:

1. Clear the cache and cookies in the browser where the issue occurs to eliminate potential session or state conflicts.
2. Verify the database connection settings in the Appian Administration Console to confirm they are accurate and that the database is accessible.
3. Examine server logs for more detailed error information that could clarify the cause of these errors.
4. Conduct tests on database connectivity and permissions to ensure that the Appian environment can execute queries effectively.

'unable to acquire JDBC connection' in many places in our application."

The errors you are encountering, particularly the "Failed to execute query in thread for: EntityBackedQueryExecutor" and "Could not open JPA EntityManager for transaction," suggest there are deeper issues with the database connection or transaction management within your Appian environment. These problems appear to be unrelated to the browser, given that they involve backend processes like entity management and database queries.

Ensure that the database server is running and accessible from the Appian server.

Double-check the database connection settings in the Appian Administration Console to ensure they are correct

Look for detailed error messages or stack traces in the Appian logs
