do you get this 100% of the time? if not, maybe you need a retry mechanism in your code

[dahuomao]

this error is Always happen，Never succeeded

[knocte]

Please post the whole exception (ex.ToString()).

[dahuomao]

chinese is "无法将数据写入传输连接: 远程主机强迫关闭了一个现有的连接。。"

[dahuomao]

translation is follow: Cannot write data to transport connection: Remote host forcibly closed an existing connection.

I said exception object (which includes stacktrace), not exception message.

@dahuomao,have u fix this?I got the same problem.

[dahuomao]

@legend2k 请用一台可以直接连接电报服务器的电脑。

[legend2k]

@dahuomao 是不是需要国外的服务器，我在本地ping 149.154.167.50 和 telnet 149.154.167.50 443都能通。没有使用任何VPN。

[dahuomao]

@legend2k 是的，需要国外服务器，本地我也可以ping通，但是就是连不上，全局翻墙也不行，找了半天，最后直接在国外服务器上跑通了。

[legend2k]

@dahuomao 多谢多谢

[dahuomao]

@legend2k 找到本地翻墙可以解决的办法了联系我记得。

[xiukun]

@dahuomao 本地翻墙如何连接 能告知吗？ qq:411560201 能加我吗 谢谢
