Hello,

I have been having an issue since Sep 23 on one of GHA jobs that were running fine prior to that date.

So, I create a simple GHA job which only build a Docker file. But for some reason, it’s timed out and never completed.

I am using self-hosted runners, and this is the GHA job: (GHA, Current runner version: ‘2.283.1’)

name: debugging-actions on: push: branches: - debugging-github-actions

jobs: build: runs-on: [tools-low] steps: - uses: actions/checkout@v2 - name: Docker build run: docker build .

Dockerfile

FROM alpine:latest
ENV KUBE_LATEST_VERSION="v1.19.9"
RUN apk add --no-cache bash bind-tools jq
RUN apk add --update ca-certificates 

&& apk add --update -t deps curl 

&& export ARCH="$(uname -m)" && if [[ ${ARCH} == "x86_64" ]]; then export ARCH="amd64"; fi && curl -L https://storage.googleapis.com/kubernetes-release/release/${KUBE_LATEST_VERSION}/bin/linux/${ARCH}/kubectl -o /usr/local/bin/kubectl 

&& chmod +x /usr/local/bin/kubectl 

&& apk del --purge deps 

&& rm /var/cache/apk/*

I think this is the answer

It seems like fastly is filtering ICMP need to frag packets, which means that PMTU does not work. This can be a problem is your traffic goes via a network link that has MTU lower than 1500 (typically tunnels/vpns, PPPoE and similar). This can be worked around by enabling tcp mss clamping in the network.

fetch of the apk index just hangs. I hit this now on a Ubuntu server and Docker… for Windows ``` Step 1/14 : FROM maven:3.3.9-jdk-8-alpine ---> dd9d4e1cd9db Step 2/14 : RUN apk update && apk upgrade && apk add --no-cache --update ca-certificates bash wget curl tree libxml2-utils putty git && rm -rf /var/lib/apt/lists/* && rm -rf /var/cache/apk/* ---> Running in 536cbd484c36 fetch http://dl-cdn.alpinelinux.org/alpine/v3.5/main/x86_64/APKINDEX.tar.gz ```
