Hello Team,  
Problem Statement - Unable to launch a ignition project.  
Ignition version - 7.9.21  
Error - SAXParseException:DOCTYPE is disallowed when the feature "[http://apache.org/xml/features/disallow-doctype-decl](http://apache.org/xml/features/disallow-doctype-decl)" set tp true.

Troubleshooting done - Deleted the .ignition folder and attempted re-launch. No change and I still see same error.

When I create a local gateway and launch the same project, it works like normal.  
Can someone please assist in resolving this issue?

I'm experiencing a similar or the same issue.

```python
Launch failed on step "ConnectStep" with error:
org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 10; DOCTYPE is disallowed when the feature "http://apache.org/xml/features/disallow-doctype-decl" set to true.

Our launch manifest does not include a doctype declaration, it’s likely something on your network is intercepting and injecting/returning its own response.
