正如标题所述，每次我尝试连接（通过 RDP）时，Remmina 只会连接一次（并且它适用于会话的剩余部分），但任何后续尝试连接到另一台甚至同一台 PC 的操作都会失败。我需要重新启动 Remmina，然后它才能再次工作。原因可能是什么？
从控制台启动 remmina 我可以看到以下输出。第一次连接成功，一切都很好。第二次就失败了。只有重新启动 remmina 才能再次重新连接。

我应该指出，我使用的是 Arch，具有所有最新更新，并且我使用的是 Remmina 1.3.4。我发现了另一个人遇到同样的问题，但这是一年多前的事了，推荐的解决方案（降级）似乎不切实际，因为它在一周前左右确实有效。
答案1
这是 freerdp 的一个错误，唯一的解决方案是降级或安装不可用的 freerdp 2.0。您可以使用 freerdp-git aur 将其安装在 arch 中。它为我解决了这个问题
答案2
+1 调整连接的 RDP 会话大小时。唯一的解决方法是杀死 Remmina 并重新启动它。
