### PyCharm SSH Connection Error Solution When encountering errors while establishing an SSH connection with PyCharm, several factors could be contributing to this issue. Ensuring that the configuration settings are correct and verifying network connectivity can help resolve these problems. #### Verify Network Connectivity Ensure there is no firewall or network policy blocking access between the local machine and the remote server. Testing the SSH connection outside of PyCharm using standard SSH tools like `ssh` from terminal helps confirm whether the problem lies within PyCharm's setup or general network issues[^3]. #### Check Configuration Settings in PyCharm In PyCharm, navigate through the deployment configurations where one needs to specify details about the remote host including hostname/IP address, username, password (or private key), and port number typically being 22 unless otherwise specified by system administrators. Incorrect entries here will lead directly to failed connections. #### Utilize Key-Based Authentication Instead of Passwords Switching over to use keys instead of passwords for authentication purposes often resolves many common connection troubles because it avoids potential typos during login attempts. Generate a pair of RSA/DSA keys locally then copy public part onto authorized_keys file located inside .ssh directory under home folder on target Linux-based servers. ```bash # On Local Machine ssh-keygen -t rsa -b 4096 -C "your_email@example.com" ssh-copy-id user@remote_host ``` #### Adjust Timeout Parameters Appropriately Sometimes increasing timeout parameters might also solve transient disconnection issues especially if working across geographically distant locations causing higher latency times than usual. Modify `.ssh/config` adding lines below: ```plaintext Host * ServerAliveInterval 60 TCPKeepAlive yes ``` This ensures periodic activity checks keeping sessions alive longer without dropping unexpectedly due solely based upon idle time alone[^1]. #### Enable Debug Logging Within PyCharm Enabling debug logging within IDE itself provides more insight regarding what exactly goes wrong internally leading up until failure point occurs making troubleshooting process easier overall.
