# Connection errors
{% cut "**Site doesn't open**" %} {#site-connection}
{% cut "Check your network status" %}
Network restrictions may prevent you from accessing the site. Those might be caused by software (antivirus programs, firewalls, or viruses), or network settings on the provider side (such as proxy servers).
Check whether you can access the site on another computer from a different network to make sure that the site works. If the site fails on your computer only, we recommend contacting your system administrator or your provider's support. If you can't open the site only in Yandex Browser, temporarily disable your antivirus or firewall. They might be blocking the connection.

{% cut "**How can I clear the SSL cache?**" %} {#troubleshooting__clear-ssl-cache}
You can't clear the SSL cache using Yandex Browser tools because it uses the system certificate store.

{% endcut %}
{% endcut %}
{% cut "**Where is Turbo mode?**" %} {#turbo-mode}
Yandex Browser used Turbo mode to speed up access to various sites, but it only worked over the HTTP protocol. There are very few such sites left now, so we turned off Turbo mode in Yandex Browser and removed it from settings.
We have already added other ways to speed up your browsing. They'll help Yandex Browser stay fast without a special mode and further improve page loading speeds.
