How can we help you?
I added a link to the website. Why doesn't the website open?
Check the correctness of the link. Links to the site look like https://taplink.ru.
If you get a certificate error or similar - try to insert a link with HTTP prefix instead of HTTPS - http://taplink.ru. Keep in mind, the site must be opened via https to go from Instagram browser, if it gives an error - check if the SSL certificate is correct on the side of your site (where you put the link).
It could be that your site is too heavy for the built-in Instagram browser. To check, open your Taplink through a full-featured browser (Chrome, Safari, or from your computer) and follow the link to the site. If it opens but doesn't work from the app, the reason is your site. To check, you can paste the link to the desired site to your Instagram profile and see if the jump will work from the app. If the link doesn't work, the reason is on your site.
