Error 504 on static site generation (WP2Static)

[fazalfarhan01]

Hey there.

The static site generation used to work fine but i am not able to run it from a few hours.

I get this error:

504 error code returned from server.
Please check your server's error logs or try increasing your 
max_execution_time limit in PHP if this consistently fails 
after the same duration.
More information of the error may be logged in your browsers console. 

And this is what I get in the console:

Why is http being appended to customer-care-solution.com? And how do I solve this?

My setup:

1. Lokl site with a reverse proxy running on https.
2. Static site accessible on customer-care-solution.com.
3. Modified host files on my computer to point to dynamic WordPress site.

[fazalfarhan01]

Found a workaround

• Used the scheduled jobs queue to generate static site with out errors.
• But generating from Run -> Generate results in 504

[leonstafford]

@fazalfarhan01 I've moved this into WP2Static repo for now. It may still be related to this network connectivity issue

But, I really should improve the error handling in WP2Static to provide better feedback about the cause when you're running via the UI and to add some re-attempts on URL crawls if not already, which may have fixed this issue, where it looks like it wasn't able to connect to customer-care-solution.com.

[jakob-lundberg]

I don't think this is related to connectivity issues. It looks like the domain it is trying to resolve is customer-care-solution.comhttp and not customer-care-solution.com

[leonstafford]

Probably due to the https reverse proxy? (sorry, just read/digested the part at the end about about your setup now)

Common to WP2Static, is that it needs the Site URL of the WP site to be the same that it's crawling, as much logic relies on that.

So, yeah, that setup is not supported today. Whether it is possible is another matter.

[leonstafford]

Sorry, brain not functioning well at end of day, but that is the general issue here. If you're able to keep the WP Site URL the same as the URL it's served from and WP2Static crawls, then it should be fine.

[ZhymabekRoman]

Same error Is there any solution?

[leonstafford]

@ZhymabekRoman quick solution will be to change environments. You can try https://lokl.dev and import your site there or use any other VPS.

If issue persists, try with default WP site. Then re-enable piece of your site until problem reoccurrs, then we will know the exact cause.

@ZhymabekRoman did you try this?
