我们发布了一个移动应用程序，我们的一些用户无法连接到我们的应用程序。首先，我们认为这是一个dns问题，因此我们将DNS从数字海洋更改为Cloudflare，但它没有解决任何问题。 在Android设备上，我们使用Retrofit 2.4连接到我们的服务器。但是我们的某些用户无法连接到服务器，但是他们在服务器上执行ping操作，并且可以在浏览器中打开网站，但只能使用vpn进行连接。
我们从firebase获得了此异常，我们使用Retrofit 2.4.0和OKHTTP 3.10.0。他们的问题在github或网上都没有。

您缺少的是超文本，您应该使用完整的url，以便 系统可以知道您是连接到本地PC还是服务器。本地网址可以是C：//jomlex.com/，或者远程网址可以是https://jomlex.com/。
由于您使用的是远程服务器，请使用 https://jomlex.com/
