If you encounter an error message from Portainer stating that a stack with the specified or normalized name 'helmut4' already exists, you might need to address the issue on the server-side.
This issue can arise if Portainer running version 2.9 or earlier has been upgraded to a newer version. In previous versions, it was permissible to create stacks with uppercase letters, such as "Helmut4." However, this functionality has been modified, and only lowercase characters are now permitted, resulting in the name "helmut4."
Please exercise caution, as the following steps may result in data loss, corruption, or other unexpected issues.
Proceed only if you are thoroughly acquainted with the task and are fully aware of the potential risks.
