| Error message | Likely meaning (TL;DR) | Recommended next steps |
|---|---|---|
| Failed to open TCP connection to www.slack.com:443 (execution expired) | The request to www.slack.com:443 timed out, so the server couldn’t complete an outbound HTTPS connection (network/DNS/proxy/firewall issue). | Verify outbound connectivity from that host to www.slack.com:443 (allow it through firewall/proxy, ensure DNS resolves, and confirm your proxy settings if used). |
| Internal Server Error when clicking Save templates (Messages stage) | The stage did not save. The most common cause is a Channel that was never stored — picking a channel and clicking Next instead of Update leaves the integration without one. | Go back to the Channel stage, re-select the channel and click Update, then return to Messages and click Save templates again. If the error repeats, contact Xyte support with the time of the attempt. |
| Slack warns that the Xyte app is not approved / the install is pending | The workspace restricts app installations. Xyte is not listed in the Slack Marketplace, so Slack holds the install until a workspace admin approves the app. | Ask a Slack workspace admin to approve the Xyte app request (Slack admin → Manage apps), then run the Connect stage again. |
