503 Error

Hi again @reneesoffice,
Finally, I figured out the problem.
definitely it is not related to amp plugin, happy to say that.
The issue is related to wp super cache, which I am not happy to say because this is an auttomatic official plugin and I had to pass to a new one and searching for it.
Problem resolves after disabling caching, and when I enabled back problem occurs again.
You might test on your end with super cache and contact with them for solution may be.

Sorry for taking your time, and thanks for your effort to resolve the issue.
Happy to resolve it.

Can you share how you have configured WP Super Cache to cause the error? As far as I know WP Super Cache works with the AMP plugin.

A 503 error typically means there will by some PHP error added to the error log. If you can obtain that it will help with identifying what is going wrong.

Hi @westonruter

unfortunately, I have uninstalled the super cache plugin, and now installed total cache seems total cache working. (since the site has huge traffic I can’t use it as test environment:(( )
Additionally, on some forums and plugin comments, I see that super cache is not compatible with amp plugin.
On the other hand, some of my other websites I am using an alternate amp plugin that does not has this issue with super cache.
cheers!
