[Ameen_Dev]

After downloading and installing the package from the git I am getting this error - "HTTP ERROR 503 AuthenticationSupport service missing. Cannot authenticate request.". I tried steps based on this discussion -> https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/http-error-503-authenticat...

But nothing worked. Please help me to solve this issue.

Are you able to open crx/explorer?

[Ameen_Dev]

No I cannot open the crxde. And I am getting the same error "HTTP ERROR 503 Service Unavailable"

[Himanshu_Jain]

Shut down the instance and remove index files in crx-start/repository folder and restart it.

[Ameen_Dev]

Tried already but no luck. Still it is not working.

[Himanshu_Jain]

Are you able to access (http://localhost:4502/system/console/bundles/)?

[Ameen_Dev]

yes I can access the above URL and see the bundles.

Any solutions? Please share.

please make sure you are using correct version that your project archetype supports. Install a stable service pack before installing your project from GIT.

I found the cause of this issue. It happened because of the unwanted components that occupied the page while doing authoring. After removing that unwanted components, it was working fine. Thanks everyone for the support.
