If you are experiencing problems with uploading or downloading, your networking might be blocking some of the Dash services. This typically can happen in corporate networks and company-provided VPNs where access to websites is restricted and managed by a central IT team.
If you are experiencing these sorts of problems, please ask your IT team to "whitelist" the following domains:
They will also need to make sure that the firewall is not blocking WebSockets (wss://) for the above domains.
Emails are sent from the domain @dash.app, so this should also be whitelabelled in your email server spam filters.
If you still have problems after doing this, please get in touch and we will be happy to help you resolve this.
