To make sure Slickstream works properly on your site, our servers need to be able to access your pages without being blocked. **If Slickstream is unable to complete the indexing process, it’s likely that a firewall, security plugin, or CDN (like Cloudflare) is blocking our requests.** The most **common overlooked issue** is that **the server is blocking our bot based on its user-agent.** Follow these steps to allow Slickstream to work correctly. #### **Step 1: Allowlist Slickstream’s IP Addresses** Slickstream’s servers use the following IP addresses. These should be allowlisted in your firewall, CDN, and security settings: **Primary IP Ranges:** ``` 51.161.98.0/2651.161.44.128/2651.222.63.128/26 150.230.164.215/32 ``` If your firewall doesn’t support CIDR notation, your hosting provider can apply the ranges for you. --- #### **Step 2: Allow Slickstream’s User-Agent** Even if Slickstream’s IPs are allowlisted, some security settings may still block our bot based on its user-agent. This is a common cause of 403 errors. **User-Agent to Allow:** ``` Mozilla/5.0 (compatible; SlickBot/1.0; +http://slickstream.com) ``` #### **Where to Check:** - **Cloudflare**: Go to **Security \> Bots** and ensure SlickBot isn’t being challenged or blocked. - **Wordfence (or other security plugins)**: Check **Advanced Firewall Options** and add SlickBot to the allowlist. - **Host-level bot protection:** Some managed hosts have automated “bad bot” filters that require manual allowlisting. *If unsure where to change this, use the email template below to contact your hosting provider.* --- #### **Step 3: Allowlist Slickstream in Common Security Tools** ###### **Cloudflare** 1. Log in to Cloudflare. 2. Select your site and navigate to **Security \> WAF**. 3. Click **Create a Firewall Rule** and configure: - **Field**: IP Address - **Operator**: is in - **Value**: *one of the Slickstream IP ranges* - **Action**: Allow 4. Click **Save and Deploy**. 5. **Create a rule for *each* IP range** ###### **Wordfence (or Other Security Plugins)** 1. Log in to WordPress. 2. Navigate to **Wordfence \> All Options \> Allowlisted IPs**. 3. Add`` ``` 51.161.98.0/26 ``` 4. Click **Save Changes**. ###### **Sucuri Firewall** 1. Log in to Sucuri. 2. Select your site and go to **Security \> Access Control**. 3. Under **Allowlisted IP Addresses**, enter ``` 150.230.164.215/32 ``` 4. Click **Save Changes**. --- #### **Step 4: Ask Your Hosting Provider for Help** If you lack access to firewall settings or need assistance, ask your hosting provider to allowlist Slickstream’s IPs and user-agent using the template below: **Email Template for Hosting Support** **Subject:** Please Allowlist Slickstream’s IPs and User-Agent > Hi \[Hosting Provider’s Support Team\], > > We are working with Slickstream, a trusted service that enhances site search and engagement. However, our site is currently blocking their bot (`SlickBot/1.0`), leading to 403 Forbidden errors. > >   > > Can you allowlist the following IP range to allow Slickstream to access our site? > > 51.161.98.0/26 > 51.161.44.128/26 > 51.222.63.128/26 > 150.230.164.215/32 > >   > > Additionally, please ensure that our security settings are not blocking the following user-agent: > > `Mozilla/5.0 (compatible; SlickBot/1.0; +http://slickstream.com)` > >   > > If a firewall, WAF, or bot protection is enabled, please adjust the settings to allow Slickstream’s bot. > >   > > Thank you for your help! --- - For details on how to allowlist IP addresses in Cloudflare see [https://support.cloudflare.com/hc/en-us/articles/217074967-Configuring-IP-Access-Rules](https://support.cloudflare.com/hc/en-us/articles/217074967-Configuring-IP-Access-Rules). - For details on how to allowlist IP addresses in Cleantalk see [https://cleantalk.org/help/blacklist-usage](https://cleantalk.org/help/blacklist-usage). - For details on how to allowlist IP addresses in Sucuri see [https://docs.sucuri.net/website-firewall/whitelist-and-blacklist/whitelist-an-ip-address](https://docs.sucuri.net/website-firewall/whitelist-and-blacklist/whitelist-an-ip-address/). --- #### **Need Help?** If you’ve followed these steps and Slickstream is still being blocked, contact us at **support@slickstream.com**. ## Related Articles [![Adding Slickstream to Squarespace](https://www.slickstream.com/hubfs/Slickstream%20and%20Squarespace.png)](https://www.slickstream.com/support/how-to-add-slickstream-to-squarespace) [Engagement Suite](https://www.slickstream.com/support/tag/engagement-suite) [Documentation](https://www.slickstream.com/support/tag/documentation) ### [How To Add Slickstream To A Squarespace Website](https://www.slickstream.com/support/how-to-add-slickstream-to-squarespace) This [article](https://support.squarespace.com/hc/en-us/articles/205815908-Using-code-injection) from Squarespace support explains how to add code to a Squarespace site.
