r/ClaudeAI on Reddit: Claude MacOS Desktop App shows "Internal Server Error" while web version is working
June 8, 2025 -
Been having this issue for the whole day. I tried removing or disabling some MCP servers; nothing has worked so far... I have not tried reinstalling the app yet
Anyone facing the same issue. Is there a log for the desktop app?
Update as of 2025-06-08: Looks like after the series of new feature releases, especially the extended Project Knowledge Base capacity (via RAG), the issue has not happened again so far. I did not make any changes to my MCP configs either

Is your card info showing you from another location than the VPN?

Connect via the VPN to a country that is allowed according to their Terms and services. Basically any country outside EU. Then choose Google Pay as an option. Make sure you have a card added to it. I think you can do that via your Google account or somewhere in Chrome browser. Then the payment should com through. I've been trying for weeks now, and only this option worked. I even opened different bank accounts to try different cards. In the end Revolut card worked that is registered in the EU.

I tried the following setup and this worked. Perhaps this was a path issue.
% which node
/usr/local/bin/node
{
"mcpServers": {
"filesystem": {
"command": "/usr/local/bin/node",
"args": [
"/usr/local/lib/node_modules/@modelcontextprotocol/server-filesystem/dist/index.js",
"/Users/xxx/Desktop"
]
}
}
}

I also ran into this issue. In my case, the problem was caused by old versions of node that were still installed (via nvm). After cleaning the old installation the issue was resolved.

r/ClaudeAI on Reddit: Internal Server Error when Claude finishes response
March 6, 2025 -
Hi Everyone, I'm relatively new to Claude but used all other AI competitors before. Somehow when I use Claude it just wont give me a response. It starts thinking and even writing the reponse, but when it finishes i just recieve an "Internal Server Error". I tried using another browser (Firefox and Edge), also restarting the browser. I also tried resetting my IP.
Does anyone else has this issues? Is there any fix?

For me it just fails to proceed with multiple queries starting today. Rephrasing sometimes help, but often fails later. Like "give me a topic for this email" that I've pasted before, it just fails with Internal Server Error

So, I tried the Filesystem MCP server, and it also has the same problem. Claude says it can't help resolve the problem. I tried the MCP Inspector, but that can't connect either, so debugging is not possible. Below is a section of the log file: 2025-05-19T06:36:25.483Z [filesystem] [info] Initializing server...
