More useful diagnostics for custom-list failures

CalimerO — Fri, 13 Nov 2026 01:18:32 +0000

The current report omits custom-list update status and compact heap, listener and Squid reload evidence. A proposed change adds these to the diagnostics ZIP and keeps collection bounded. This helps distinguish a bad list, a proxy reload problem and a Java failure. It will not make a report available when the Java service is already unresponsive, as described in the (https://eblocker.org/community/bugs-features/eblocker-randomly-stops-working-and-no-longer-responding-potential-memory-leak/).

Make false positives easier to trace to a list

CalimerO — Fri, 13 Nov 2026 01:17:23 +0000

When a custom list blocks a site, the warning page currently shows the category but not the list name. This makes false positives difficult to diagnose. A proposed UI/backend change displays the responsible list name when known, without showing the source URL. The change is prepared for 4.0.3 and the 4.1 development branch.

Squid may reload for unchanged SSL exception lists

CalimerO — Fri, 13 Nov 2026 01:16:01 +0000

An app-module notification can make eBlocker rewrite unchanged SSL exception files and reload Squid. This is present in 4.0.3 and the current 4.1 development branch. A focused fix reloads only when the effective domain or IP list changes; both cases are covered by a test.

Repeated Squid reloads from unchanged device settings

CalimerO — Fri, 13 Nov 2026 01:14:36 +0000

I found a code path in 4.0.3 and the current 4.1 development branch that reloads Squid even when the device ACL did not change. Repeated reloads were observed during a network-stability test. A small conditional-reload fix and test are prepared. This may contribute to short interruptions, but it does not yet explain every symptom in the (https://eblocker.org/community/bugs-features/eblocker-intercepting-traffic-on-disabled-devices/).

Custom-list format and update safety

CalimerO — Fri, 13 Nov 2026 01:13:03 +0000

An incompatible list format can reach eBlocker's filter parser, and a failed update does not always keep the previous working list. For example, the large (https://malware-filter.gitlab.io/malware-filter/urlhaus-filter.txt) remained at `INITIAL_UPDATE` in my test. This behavior is present in 4.0.3 and the current 4.1 development branch. I prepared a validation and rollback patch; the proposed size limits still need maintainer review. The separate (https://eblocker.org/community/bugs-features/eblocker-randomly-stops-working-and-no-longer-responding-potential-memory-leak/) remains under investigation.

Custom EasyList: an empty rule can block unrelated websites

CalimerO — Fri, 13 Nov 2026 01:11:47 +0000

I reproduced a parser error in eBlockerOS 4.0.3 with the (https://raw.githubusercontent.com/uBlockOrigin/uAssets/master/filters/annoyances.txt): a blank rule can match every URL. The same code is present in the current 4.1 development branch. A small fix and regression tests are prepared. Until it is released, disable the affected custom list if unrelated sites show tracking or malware warnings.

eBlocker Randomly stops working and no longer responding (potential memory leak?)

jimmysofat6864 — Wed, 04 Nov 2026 19:42:45 +0000

Before, my eBlocker setup was fairly reliable but I am not sure if it was a recent update or a memory leak or something but randomly, my eBlocker will stop intercepting traffic from my phone and advertisements will leak through. And when I check my eBlocker, it will just show a loading icon and no way to configure the eBlocker unit itself. I can press the power button on the unit itself and it will reboot my unit but register itself as a hard unplug when it wasn't.

It wasn't an issue a month or two ago when I got started but it seems to be a recent issue and presents itself randomly about after a day of use. I have some pictures and screenshots showing what happens when the issue occurs. On my phone, I just get a loading icon but on my desktop, I get a white screen or an error message.

DNS stopped working with active TOR network

JoxWayne — Wed, 04 Nov 2026 15:07:07 +0000

Hello,

I am wondering, if anyone else has the same problems, that I have since some days.

When I activet TOR network for my device, I cannot reach any internet site. Deativating TOR makes everything working again.

I did some tests on my PC and the first one was a nslookup wich directly failed. I also find it strange, that the DNS server name changes from eblocker.box to www.ebloker.box

TOR inactive:

nslookup eblocker.org
Server: eblocker.box
Address: 192.168.0.xxx

Name: eblocker.org
Addresses: 2a03:b0c0:3:f0:0:1:1bbe:3000
174.138.100.168

TOR active:

nslookup eblocker.org
Server: www.eblocker.box
Address: 192.168.0.xxx

DNS request timed out.
timeout was 2 seconds.

Tor fails on eBlockerOS 3.2.3 and 4.0.3: required Desc=3/Microdesc=3 protocols unsupported #460

CalimerO — Tue, 03 Nov 2026 08:37:45 +0000

@bpr

I tested Tor on eBlockerOS 3.2.3, 4.0.3 and two existing 4.1.0 test VMs on 3 November 2026.

After installing all offered updates, 3.2.3 (Tor 0.4.5.16) and 4.0.3 (Tor 0.4.7.16) both fail. The Tor service exits because the network requires Desc=3 Microdesc=3, which these versions do not support. On both systems, the dashboard nevertheless shows “Connected.”

The two eBlockerOS 4.1.0 VMs have Tor 0.4.9.11. Both reached 100% bootstrap, and an HTTPS request to torstatus.greensec.de through their Tor SOCKS socket returned HTTP 200. I have not yet tested traffic from a separate device routed through eBlocker.

The reproduction steps and the 4.1.0 follow-up are in GitHub issue #460.

Best regards
Sven

eBlocker Intercepting Traffic on Disabled Devices

jimmysofat6864 — Sun, 01 Nov 2026 05:35:35 +0000

I have eBlocker disabled in the settings for my Windows PC but I have it enabled for other devices on the network. But for some reason, eBlocker is still trying to intercept traffic from my Windows PC. When this occurs, I get DNS errors, page loading errors, or I get this error message saying "ERR_ICAP_FAILURE"

Since this machine is set to exempt, eBlocker should have completely bypassed my machine and not process it but it is still trying to process requests from my PC.

This doesn't seem to be an issue for the say first few hours of operation but given maybe a day or two, certain web requests such as clicking links in gmail lead to a page that never loads followed by the eBlocker error message which should have never been displayed in the first place since it's disabled in the eBlocker device settings.

The error message I see on the device with eBlocker disabled is as follows.

ERR_ICAP_FAILURE
Q0xUX1JFUU1PRF9BQk9SVA== (CLT_REQMOD_ABORT)

Expected Behavior:

When a device is set to "Not Protected", eBlocker should immediately cease sending gratuitous ARP replies for that host, stop proxying outbound HTTP/HTTPS traffic, and allow direct Layer 2/3 routing to the actual default gateway.

Current Behavior:

Certain web links time out and fail to load. Or in my case, I was restoring an iPhone in recovery mode via iTunes/Apple Devices/3uTools and I kept getting itunes error 1109. After extensive poking around and confirming that my eBlocker was disabled, the only way for me to restore and wipe my iPhone via iTunes was to power off my eBlocker and my iPhone restored successfully and the webpages I was trying to view loaded correctly.
