Some companies restrict access to external websites or file downloads through internal firewalls or security policies. This can result in errors such as “403 Forbidden” or blocked downloads — especially for file types like XLSX, XLSM, ZIP, password-protected files, or encrypted PDFs.

If you’re unable to open files or access the data room, contact your IT department and ask them to allow the following domains:

If the issue persists, ask your IT team to check for restrictions on file types, including PDF, DOCX, XLSX, ZIP, and encrypted files. As a temporary workaround, try downloading files using a personal device on a non-corporate network.

To ensure full access to the data room, your IT team may need to allow traffic to specific regional servers. Each project is hosted on a particular server, and access may be blocked if these are restricted by firewall or network settings.

Please ask your IT department to allow the following domains:

Regional servers:

Each of these also has a corresponding API domain, such as:

Content delivery (for static files):

If you're unsure which one is relevant to your project, we recommend allowlisting all of them to avoid interruptions.

If you suspect firewall or network restrictions are the issue, try the following steps:

If the data room loads correctly using any of these alternatives, it’s likely that corporate restrictions are blocking access. In that case, please forward these allowlist instructions to your IT department. You can continue using the alternate device/network as a temporary workaround.

If you’re copying and pasting a login link, make sure it hasn’t been accidentally modified — for example, with extra dots or repeated segments.

Same as with access to external resources, emails from Ideals may be blocked by filtering (anti-spam) settings of your corporate inbox.

In this case, we recommend adding @idealsvdr.com, @mandrill.idealsvdr.com, and @mailer.idealsvdr.com domains and our IP address 198.2.186.123 to the allowlist so that messages from us do not get blocked and all the notifications are received.

If you use a non-corporate email address (@gmail.com, for instance), make sure the emails did not land in a spam folder and mark them as not spam to ensure further delivery.

In case your users did not receive invitations to the data room, try resending the invitation email.
