Troubleshooting Common Problems on Nexus

You cannot sign in

1. 1Double-check the email address and password — passwords are case-sensitive.
2. 2If you registered with email and password, make sure you completed the one-time code verification step. If the code never arrived, check your spam folder and use the resend option on the verification screen.
3. 3If you signed up with Google, use the Google button rather than typing a password — Google accounts and email/password accounts are separate sign-in methods, even when the email address is the same.
4. 4Forgot your password? Use the "Forgot password" link on the sign-in page, then check your inbox (and spam folder) for the reset link.
5. 5Still stuck? Send us a message from the Support page with the email address you registered with and what you see on screen.

You are signed in but see no communities

The server list on the left shows communities you own or have joined. A brand-new account has none yet. Either create a community with the + button, or join a public one from the Discover page (compass icon in the sidebar). If a friend told you they created a server and you cannot see it, make sure you have actually joined it — public servers must be joined from Discover before they appear in your list.

Messages are not appearing

• •Check you are in the right channel — the channel name is shown at the top of the chat.
• •If you used the search bar, remember it filters the conversation: clear the search field to see all messages again.
• •Nexus updates conversations in real time. If something looks stuck, a normal page refresh usually fixes it.
• •If only one message is missing, its author may have edited or deleted it.

You cannot create a channel

Channel creation is limited to the server's owner, admins, and moderators. If you do not see the + button next to a category, you are a regular member of that server. If you believe you should have permission, ask the server owner to check your role.

File uploads fail

• •Very large files may fail to upload — try a smaller file or a compressed version.
• •Supported attachments are everyday documents and images. Unusual file types may be rejected.
• •If an upload fails once, simply try again — temporary network hiccups are the most common cause.
• •If a specific file consistently fails, contact support with the file type and size.

Attachments you send are stored privately: recipients open them through the app with an expiring secure link, so files are not accessible to strangers through a public URL.

The unread badge will not clear

Unread badges in your direct-message list count messages you have received but not opened. Opening the conversation marks those messages as read. If the badge persists after opening the chat, refresh the page.

Still stuck? Get in touch

The Support page has a contact form for bug reports, feature requests, and account questions, plus an email address if you prefer. When you write to us, include: what you did, what you expected to happen, and what happened instead. Screenshots help enormously. We read every message, though we cannot promise an instant reply.
