Slow response time when sending URL via SendMessage API #277

Open Martin22 opened 1 month ago

Martin22 commented 1 month ago

Hi. If I send a URL, for example, https://google.com/, as a string via the SendMessage API endpoint, I experience a 7-second delay before the curl command completes. The same issue occurs when using Swagger. It seems like it's trying to resolve the domain via DNS. However, DNS resolution works everywhere else, both in Docker and on the host machine, so it doesn’t appear to be a DNS problem. Has anyone else encountered this issue?

I also sometimes have a slow response time of up to several hours late, and not only when sending an address

I figured out why there is a delay. The application on the phone must be running, through which the page previews are likely being fetched. If it's not running, it seems to wait for some kind of timeout, and the preview of the sent page won't load. It looks like a feature of WhatsApp, which probably can't be changed, but maybe the timeout could be shortened somehow?
