Some companies restrict external websites, file downloads, or emails through corporate firewalls and filters. This can block access to the data room, prevent downloads, or stop email notifications from reaching you.
This article shows you how to identify if restrictions are the cause and what steps you or your IT team can take.
1. Access to the data room
Corporate firewalls may block data room access or downloads with errors such as “403 Forbidden.” This is common with file types like XLSX, XLSM, ZIP, password-protected files, or encrypted PDFs.
What to do
Contact your IT department and ask them to allow:
app.idealsvdr.comauth.idealsvdr.comAll subdomains under
*.idealsvdr.com
Ask IT to check for restrictions on file types: PDF, DOCX, XLSX, ZIP, encrypted PDFs.
As a temporary workaround, try using a personal device on a non-corporate network.
⚠️ These restrictions are controlled by your organization. Our Support team cannot override them.
2. Subdomains to allowlist
Each project is hosted on a specific server. If that server is blocked, you may not be able to log in, view, or download files.
Ask your IT team to allow the following:
Regional servers
www1.idealsvdr.comthroughwww8.idealsvdr.comwww9.idealsvdr.cn(for data rooms hosted in China)
Each server also has a matching API domain, for example:
api.www1.idealsvdr.comapi.www2.idealsvdr.com
Content delivery (static files)
cdn-app.idealsvdr.com— application files (JavaScript, CSS)cdn-auth.idealsvdr.com— login and authentication
💡 Because projects can be hosted on any of these, we recommend allowlisting all to avoid interruptions.
3. How to confirm if restrictions are the issue
Head straight to our Troubleshooting tab in the Help center. This is specially designed to find these issues. If that doesn't help, you can always try one of the following:
Open the data room on a personal device, outside your corporate network.
Switch to a different network (e.g., mobile hotspot, public Wi-Fi).
Temporarily disable VPN or proxy (if allowed by your company).
If the data room loads correctly, it’s likely blocked by your company firewall. Share these allowlist instructions with your IT team.
4. Double-check the URL
Make sure the login link hasn’t been altered.
✅ Correct:
auth.idealsvdr.com❌ Incorrect:
auth..idealsvdr.comorauth.idealsvdr..com
5. Browser issues
Sometimes the browser itself is the problem. Try these checks:
Update your browser to the latest version.
Try a different browser or private/incognito mode.
Temporarily deactivate browser extensions.
Make sure browser settings allow file downloads.
Use the Troubleshooting tab in the Help Center:
Run a diagnostic.
Use the Clear cache button if prompted.
6. Email delivery issues
Emails from Ideals may be blocked by corporate anti-spam filters.
What to do
Ask your IT team to allow:
@idealsvdr.com@mandrill.idealsvdr.com@mailer.idealsvdr.comIP address:
198.2.186.123
If using a personal email (e.g., Gmail), check your Spam folder and mark emails from Ideals as “Not spam.”
If invitations aren’t received, we recommend using self-registration. Then if this doesn't work, try resending the invitation email.
7. File download issues
If downloads fail, it may not be corporate restrictions. Common causes include:
Expired download links
Downloadable archives are only available for 30 days.
Ask your project administrator to generate a new downloadable archive.
Empty downloaded archives
Delete the empty archive.
Download again, ensuring the process completes fully.
Extraction errors
If extraction fails, try an alternative tool like 7-Zip or NanaZip.
