Today I encountered something strange. Suddenly I couldn't log in, the web version logs in instantly, but when I switch to the app it shows login failed. I was panicking and tried uninstalling the app, but it still didn't work, it kept showing login error, authentication denied🙃. Later I asked a friend, and they told me to change the node. I tried that too, but it still didn't work. Does anyone know what might be causing this? Please let me know🙃.
