188BET靠谱吗When Zotero can't access the network, it's usually caused by proxy settings or security software on your computer.

188BET靠谱吗By default, Zotero uses any manually entered proxy servers or a proxy auto-config (PAC) URL in your system proxy settings.It does not automatically use Web Proxy Auto-Discovery (WPAD), or "Auto Proxy Discovery" on macOS, even when enabled in the system settings.

If you don't use a proxy to connect to the internet, you should disable all proxies in your system proxy settings.If you do need to connect via a proxy, you should verify that the system settings are correct.188BET靠谱吗Note that other software on your computer may not be using the system proxy settings, which is why other programs may still be able to connect to the internet when Zotero cannot.

188BET靠谱吗If you need to configure the Zotero proxy settings differently from the system settings, you can access the Config Editor from the Advanced pane of the Zotero preferences, apply thesame settings that you would in Firefox188BET靠谱吗(on which Zotero is based), and restart Zotero, but the default setting (network.proxy.type = 5, to use the system proxy settings) is recommended.

If using a PAC file, either automatically or with network.proxy.type = 2, and your proxy requires HTTP authentication, ensure that most or all of the hosts in188BET靠谱吗extensions.zotero.proxyAuthenticationURLsare being handled by your PAC file.188BET靠谱吗Zotero will test a random subset on each startup to trigger a proxy authentication prompt if necessary.

To use WPAD, you must set network.proxy.type to 4.

If changing proxy settings doesn't help, try temporarily disabling any security/firewall software on your system.

Some connection errors can also be caused bycertificate issueson your network.
