redirection doesn’t load

here is an example of 403 error
https://example.com/wp-json/redirection/v1/plugin/?_wpnonce=a6f8c8b68e

I can’t tell anything from an example URL.

The error message should contain details. If it was working a few days ago then something has changed on your site.

what kinda change are we talking about here?
i mean i don’t remember changing anything server-side and the only thing i can remember to have changed on website is that i deactivated redirection once and then reactivated it! could deactivation have caused this?

I really couldn’t say. However, things don’t stop working for no reason. What does the error message say? It should provide more details.

well after countless browser consoler 403 error plugin finally gave me an error saying my rest api is down and plugin won’t work till i fix it
since i’m on a shared hosting ,i checked with my hosting they said rest api is probably blocked by mistake in the country’s internet.
so here is my question : what is rest api used for in this plugin, is there a way i can use the plugin without rest api?

Can you provide the full error details? If you can provide this then I have a lot more information to work with.

> what is rest api used for in this plugin

It is used for everything the plugin does.

> is there a way i can use the plugin without rest api

No.

well according to my hosting this issue is not related to redirection plugin or any other plugin. in fact they said this kinda error is common on hosting servers located in iran(where i live) and it due to country internet censorship(according to my hosting)
also since you asked i’m gonna upload the rest api error message that plugin gave me. pls note some text are persians and other english(due to incomplete translation apparently)
